Peracids have gained interest in the water treatment over the last few decades. Peracetic acid (CH 3 CO 3 H) has already become an accepted alternative disinfectant in wastewater disinfection whereas performic acid (CHO 3 H) has been studied much less, although it is also already commercially available. Peracids have also been tested for drinking water disinfection, oxidation of aqueous (micro)pollutants, sludge treatment and ballast water treatment, to name just a few examples. The purpose of this review paper is to represent comprehensive up-to-date information about the water treatment applications, aqueous reaction mechanisms, and disinfection byproduct formation of peracids, namely performic, peracetic and perpropionic acids. and PFA have several of the qualities of an ideal disinfectant: toxicity to microorganisms, but not to higher forms of life; effectivity at ambient temperatures; stability and long shelf-life; low corrosivity; deodorizing ability; widespread availability and reasonable cost [12].PAA and PFA are colorless liquids with characteristic pungent odors. Both are thermodynamically unstable and can decompose spontaneously or explode when highly concentrated, heated, under mechanical stress or exposed to catalytic effects of impurities [1,13,14]. The recommended storage temperatures are below 30 and 20°C for PAA and PFA, respectively [6,14]. Longer carbon chain length increases stability, and thus PAA is more stable than PFA [1]. However, the O-O bond dissociation energy of PFA and PAA has been calculated to be similar: 48 kcal/mol [15]. Percarboxylic acids have typically pK a values 3-4 units higher than the parent carboxylic acids [1]. Nonetheless, PFA and PAA are corrosive [16]. ACCEPTED MANUSCRIPT ACCEPTED MANUSCRIPT 3Exposure to PAA and PFA causes irritation and possibly permanent damage to the skin (cutaneous emphysema), eyes and the respiratory system. In the skin contact, 0.2% is proposed as the no-observed-effect concentration (NOEC) for short and medium length exposure [17].When inhaled, airborne concentrations less than 0.16-0.17 ppm (0.50-0.52 mg/m 3 ) are considered to cause no irritation [17,18]. However, higher concentrations are harmful and a case study suggested that PAA could cause occupational asthma [19].The largest users of PAA on a global scale (estimated in 2013) are shown in Fig. 1. Similar numbers are not available for PFA, but it is probably used at significantly lower quantities.The largest user, the food industry, applies PAA as a disinfectant in fresh produce washing water, clean-in-place (CIP) processes, on food processing equipment, and in pasteurizers, to name just a few examples [21,22]. PFA is also a suitable disinfectant in low-temperature refrigerated food processing and storage rooms [23]. In healthcare, PAA is used for instance in Recently, methods to determine the residual PAA from wastewater were compared: the spectrophotometric method using DPD and catalase was recommended for 0.1-0.5 mg/L PAA concentrations and the cerimetric/iodometric titration...

“…It has been found that high exposure and eye contact will cause severe health problems. For the above reasons, many studies were focusing on developing reliable and commercial methods to detect its aqueous concentration (Davies and Deary, 1988;Pinkernell et al, 1996;Ruttinger and Radschuweit, 2000;Awad, et al, 2003), and to monitor its airborne concentration on a regular basis in workplace environments (Effkemann et al, 1999;Hecht et al, 2004;Henneken et al, 2006). However, field measurements of PAA are extremely sparse (Fels and Junkermann, 1993;Walker et al, 2006), and hence, the limited data restrain better understanding the role of PAA on atmospheric chemistry.…”

Abstract. Peroxyacetic acid (PAA) is one of the most important atmospheric organic peroxides, which have received increasing attention for their potential contribution to the oxidation capacity of the troposphere and the formation of secondary aerosols. We report here, for the first time, a series of data for atmospheric PAA concentrations at urban and rural sites, from five field campaigns carried out in China in summer 2006, 2007 and 2008. For these five measurements, daytime mean (08:00-20:00 LT) PAA concentrations on sunlit days were 21.4-148.0 pptv with a maximum level of ∼1 ppbv. The various meteorological and chemical parameters influencing PAA concentrations were examined using Principal Factor Analysis. This statistical analysis shows that the local photochemical production was the major source of PAA, and its concentration increased with increasing temperature, solar radiation and ozone but decreased with increasing NO x (NO and NO 2 ), CO, SO 2 , and relative humidity. Based on the dataset, several issues are highlighted in this study: (i) Because PAA is a product from the photochemical oxidation of some specific volatile organic compounds (VOCs) that lead to acetyl peroxy radicals, the importance of various VOCs with respect to the PAA formation is therefore ranked using the incremental reactivity method. (ii) The contribution of PAN thermal degradation to PAA formation under conditions of different NO x concentrations is estimated based on the chemical kinetics analysis. The result shows that PAN seems to play an important role in the formation of PAA when the NO/NO 2 concentration ratio was less than 0.2 and PAA would correspondingly have feedback on the PAN-NO x cycle. (iii) PAA and other peroxides, such as methyl Correspondence to: Z. M. Chen (zmchen@pku.edu.cn) hydroperoxide (MHP) and H 2 O 2 , usually exhibited a similar asymmetric shape typically shifted to the afternoon. However, under some conditions, H 2 O 2 diurnal cycle was out of phase with MHP and PAA. The combination of linear regression and kinetics analysis indicate that the formation and removal processes of H 2 O 2 may be different from those of MHP and PAA. (iv) Considering that PAA is the reservior of free radicals, its fate is expected to have an effect on the free radical budget in the atmosphere. A box model based on the CBM-IV mechanism has been performed to access its influence on the radical budget. We suggest that the detailed information on PAA in the atmosphere is of importance to better understand the free radical chemistry.

“…In particular, an amperometric approach for the electroanalysis of PAA and H 2 O 2 was proposed [17 -19] which encountered however some operational troubles, such as time consumption, quite low sensitivity and the involvement of several steps. Furthermore, a potentiometric method was suggested [20] which is based on the different reaction rate of PAA and H 2 O 2 with iodide ions. In spite of its higher selectivity and sensitivity, this method suffers from the fact that its response is largely dependent on the solution pH, the concentrations of I 3 À and I À and the possible presence of catalysts.…”

Simultaneous Detection of Peracetic Acid and Hydrogen Peroxide by Amperometry at Pt and Au Electrodes

et al. 2006

Based on preliminary voltammetric investigations at both Pt and Au electrodes in aqueous solutions buffered at different pH values in the range 0 -10, two possible profitable triple-pulse amperometric approaches were developed for determining simultaneously peroxyacetic acid (PAA) and hydrogen peroxide present in the same samples. At both surfaces a pulsed waveform applied at rotating-disc electrodes was adopted to take advantage on one hand of the optimized signal reproducibility achieved by this potential multistep antifouling approach and on the other hand of the constant thickness of the diffusion layer, which is necessary when the recording of time-independent currents is desired. At a rotating-disc Pt electrode an anodic selective signal was indeed recorded for H 2 O 2 alone, while PAA contents could be inferred only from the difference of convenient signals, since at all pHs explored its sole cathodic reaction could be observed at potentials coincident with those proper for the reduction of H 2 O 2 too. The same pulse approach at Au electrodes instead provided totally independent signals for the two analytes considered, thus proving to be suitable for their independent detection. In fact, H 2 O 2 alone undergoes anodic oxidation also at this surface, while the reduction of PAA occurs at potentials less cathodic than those required for H 2 O 2 . At both electrodes, the best results turned out to be achieved at pH 0 in terms of both precision (AE 2 -4%) and detection limits (0.2 -0.3 mM), as well as of linear range which extended for about three orders of magnitude. The kinetics of the equilibrium involving the generation of H 2 O 2 from the reaction of PAA with water was also evaluated, since it was suspected of making unreliable the proposed amperometric approaches.
