“…Triethanolamine (TEOA), isopropanol (IPA), ascorbic acid (LAA), and silver nitrate (AgNO 3 ) were selected as the trapping agents for holes (h + ), hydroxyl radicals (˙OH), superoxide radicals (˙O 2 − ), and electrons (e − ). 48 In the experiment, a certain amount of the capture agent was added to the solution, and the process was referred to those of the previous work. 49 It was observed that the degradation activity decreased significantly after l -ascorbic acid and AgNO 3 were added to the RhB solution (Fig.…”

“…Among the advanced oxidation processes used in water and wastewater treatment, photocatalysis, as a green chemical pathway, plays an important role as it is capable of degrading and mineralizing contaminants such as dyes, phenols and pesticides into harmless products under mild conditions (Ike et al 2002;Oh 2004;Wang et al 2009;De la Fuente et al 2010;Ameta et al 2012;Rammohan and Nadagouda 2013;Umar and Aziz 2013;Pirilä et al 2015;Liang et al 2020). This process involves chemical reactions that take place in the presence of light and a photocatalyst.…”

“…Over the past two decades, numerous studies demonstrated that heterostructured photocatalysts have shown higher photocatalytic activity, compared to individual photocatalysts, in mineralizing harmful organic substances in water (Hojamberdiev et al 2012;Ibhadon and Fitzpatrick 2013;Wang et al 2013;Dong et al 2015;Liang et al 2020). In particular, heterostructured photocatalysts based on titanium dioxide, such as ZrO 2 /TiO 2 , ZnO/TiO 2 and CdS/TiO 2 , have attracted a great deal of interest due to their higher charge separation efficiency and their UV-visible light photocatalytic activity (Xu et al 2006;Chen et al 2008;Gao et al 2009).…”

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.

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
