“…The maximum removal was obtained with 0.015 M Ce(III) in the electrolyte 0.2 M H 2 SO 4 , and the potential 6 V. With treatment time 1.5 h, the removal was 80-90%, but it was even slightly higher in the absence of Ce(III) ions. Setiyanto et al (2018) offered no explanation for this finding. The information on the measurement method for the concentration of the pollutant is missing as well.…”

Since the 2000s, among organic contaminants, alkylphenols and alkylphenol polyethoxylates have been listed as hazardous substances by several national, European and international agencies because they are considered endocrine disruptors. Among the molecules classified as priority substances in terms for monitoring and action, nonylphenols and octylphenols and their polyethoxylated derivatives receive particular attention, especially in developing countries. Effluents from treatments plants are considered to be the largest source of alkylphenols in the environment. Although legislation concerning their use has become increasingly strict, these substances are still found in the environment, especially in water resources.The existing water and wastewater treatment plants have not been designated for these emerging contaminants. Conventional treatments such as biodegradation, sand filtration, carbon adsorption and/or chemical oxidation in place are not effective in their elimination removal. No appropriate methods have been developed to deal them at the urban or industrial scale. Thus, alkylphenols have become a relevant research topic for scientists interested in water engineering issues related to

“…Applicability of the approach for wastewater treatment was justified by calculation of operational costs, although the process was tested only on synthetic solutions without interferences. Setiyanto et al (2018) studied mediated electrochemical oxidation of nonylphenol ethoxylate with and without addition of cerium ions. Ce(III) ions were oxidized to Ce(IV), which then oxidized the pollutant.…”

Innovative technologies to remove alkylphenols from wastewater: a review

Alkylphenols and alkylphenol polyethoxylates are emerging hazardous contaminants due in particular to their endocrine-disrupting properties. These compounds originate from consumer products such as paints and latex paints, adhesives, inks, formulation of pesticides, paper industry, textile and leather industry, petroleum recovery chemicals, metal working fluids, personal care products, washing agents, cleaners, and detergents. Since classical wastewater treatments have not been designed to remove alkylphenols, these compounds end up polluting ecosystems. Here we review three advanced methods to remove alkylphenols and derivatives. First, innovative polymers, such as cyclodextrin polymers and molecularly imprinted polymers, allow to remove alkylphenols from effluents by adsorption. Second, biotechnologies such as microalgae, biodeg-radation in constructed wetlands and sequential anaerobic-aerobic digestion treatments. Third, advanced oxidation processes to degrade recalcitrant alkylphenols, e.g., ozone-carbon coupling, electrochemical degradation, photocatalysis, zero-valent iron-activated persulfate coupling, and catalytic ozonation.

“…Many scientific investigations have reported the emerging potentials of electrochemical method for solving analysis problems, studying reaction mechanisms as well as performing organic compounds degradation (Setiyanto et al, 2011;Azab et al, 2019;Kassa and Amare, 2019;Setiyanto et al 2020). In addition, electrochemical method offers a rapid, an efficient and a low-cost degradation of organic compounds (Matheswaran et al, 2008;Möhle et al 2018;Syaifullah et al 2018;Setiyanto et al, 2018). A study reported that mediated electrochemical oxidation (MEO) is one of a suitable-processes for destruction of organic pollutant.…”

Methylene blue (MB) is often used in textile industries and is actively present in the wastewater runs-off. Recently, mediated electrochemical oxidation (MEO) offers a fast, reliable and promising results for environmental remediation. Thus, we aimed to evaluate the electro-degradation potential of MB by MEO using Ce(IV) ionic mediator. Furthermore, we also observed the influence of addition Ag(I) ion catalyst in MEO for degradation of MB. The electro-degradation of MB was evaluated by cyclic voltammetry technique and was confirmed by UV-Vis spectrophotometry, high performance liquid chromatography (HPLC) analysis and back-titration analysis. The results showed that in the absence of Ag(I) ion catalyst, about 89 % of MB was decolorized within 30 min. When 2 mM of Ag(I) ion catalyst was applied, the electro-degradation of MB was increased to maximum value of 100%. The UV-Vis spectrum confirmed the electro-degradation of MB as suggested by decreased maximum absorbance value at λ 668 nm from 2.125 to 0.059. The HPLC analysis showed the formation of five new peaks at retention time of 1.331, 1.495, 1.757, 1.908, and 2.017 min, confirming the electro-degradation of MB. The back-titration analysis showed about 52.9% of CO2 was produced during electro-degradation of MB by MEO. More importantly, more than 97% of Ce(IV) ionic mediator were recovered in our investigation. Our results showed the potential of MEO using Ce(IV) ionic mediator to improve the wastewater runs-off quality from textile as well as other industries containing methylene blue.
