“…Potential-based sensors or the so-called “ion selective electrodes” (ISEs) have been extensively introduced in different analytical applications, such as in clinical analysis [15,16,17,18,19], environmental monitoring [20,21,22,23,24,25], pharmaceutical analysis [26,27,28,29,30,31], and quality control criteria [32]. This class of analytical devices is characterized by their low cost, high reliability and validity, and ease of operation.…”

Herein, we present reliable, robust, stable, and cost-effective solid-contact ion-selective electrodes (ISEs) for perchlorate determination. Single-walled carbon nanotubes (SWCNTs) were used as solid-contact material and indium (III) 5, 10, 15, 20-(tetraphenyl) porphyrin chloride (InIII-porph) as an ion carrier. The sensor exhibited an improved sensitivity towards ClO4− ions with anionic slope of −56.0 ± 1.1 (R2 = 0.9998) mV/decade over a linear range 1.07 × 10−6 – 1.0 × 10−2 M and detection limit of 1.8 × 10−7 M. The short-term potential stability and the double-layer capacitance were measured by chronopotentiometric and electrochemical impedance spectroscopy (EIS) measurements, respectively. The sensor is used for ClO4− determination in fireworks and propellant powders. The results fairly agree with data obtained by ion chromatography.

“…Surfactants are worldwide used in all branches of industry from domestic use (household products, personal care products and pharmaceuticals) to petroleum products and. Their extensive application translated in a large production of surfactants waste represents a global environmental problem (Bosnar & Čačić 2014). Considerable amount of surfactants are released in rivers, where they could accumulate (up to 30 µg/Ls) causing serious problems inducing pollution of the aquatic systems (Odokuma & Okpokwasili 1997).…”

“…The aim of this study was to quantify the presence of anionic and nonionic surfactants in domestic wastewaters from different counties of Romania (Ilfov, Prahova, Giurgiu, Dambovita and Arges) during three seasons (winter, spring, and summer) of 2018. Considering the fact that about 90% of the total production of synthetic surfactants comes from the sum of anionic and nonionic surfactants (Bosnar & Čačić 2014).…”

Surfactants are substances that reduce surface tension and they are worldwide used in all branches of industry such as householder products, cosmeticals, pharmaceuticals, petroleum. The large utilization of surfactants is reflected in their accumulation in the domestic and industrial wastewaters and subsequently into the waste waster treatment plants (WWTP) and the environment. Once in the environment, the surfactants could harm it by inducing important changes in water quality which could directly affect the human life. This paper is a monitoring study of anionic and nonionic surfactants from domestic wastewaters during three seasons (winter 2018, spring 2018 and summer 2018). The samples were taken from specific sampling points along Romanian counties: Ilfov, Prahova, Giurgiu, Dambovita and Braila. The results showed that the concentration of the surfactants varied between 0.85 mg/L and 6.73 mg/L for anionic surfactants and 0.81 mg/L up to 6.48 mg/L for nonionic surfactants related to the accepted value of surfactants concentration (as sum of anionic and nonionic) of 25 mg/L (Romanian legislation, HG 352/2005, NTPA 002 and Annex 2/2005). Moreover, the study revealed that the highest concentration of both anionic and nonionic surfactants were detected in Dambovita County during summer.

“…For instance, detergent can be determined by chemical sensor with impedance titration, 12 and some other sensing techniques that based on electric potential, current, conductance, piezoelectricity and photochemistry have been reported. [13][14][15] However, there are some limitations in sensor measurement. During the sensing process, the sensors need to contact with the measured object, and it requires a large number of liquid sample.…”
