Characteristic emerging pollutants at low concentration have raised much attention for causing a bottleneck in water remediation, especially complex matrices where high of interferents coexist. In the future, tailored treatment methods are therefore increasing significance accurate removal target different matrices. This critical review focuses on overall strategies accurately removing highly toxic presence typical interferents. The main difficulties hindering improvement selectivity analyzed, implying that it is difficult to adopt universal approach multiple targets and substrates. Selective based assorted principles proposed aiming improve anti-interference ability. Thus, approaches fundamentals achieve subsequently summarized including their mechanism, superiority inferior position, application scope, method bottlenecks. results show may be applicable certain conditions pollutants. To better understand mechanism each selective further select appropriate method, advanced qualitative quantitative characterization presented. processes adsorption, interaction, electron transfer, bond breaking discussed. Some comparable helpful promoting development related fields. research framework its established. Presently, although continuous advances remarkable achievements been attained characteristic organic pollutants, there still various substantial challenges opportunities. It hopeful inspire researches new generation wastewater technology, which can selectively preferentially treat establish reliable lead direction environmental science.

Water reuse for irrigation activities is becoming a crucial worldwide challenge due to the depletion of water sources. Anyway, agricultural drainage can potentially contain dangerous contaminants such as metals, pesticides, and herbicides, including atrazine. To address need agriculture wastewater purification, we investigated atrazine removal from simulated by electro-oxidation using platinum-coated titanium electrodes on lab-scale experimental apparatus. The effects electrolyte composition concentration, i.e. ionic strength applied current density removal, were investigated. results demonstrated that electrochemical oxidation herbicide occurred through two routes, depending presence or absence oxidizing chlorine species. generation intermediates during treatment was monitored quantified evaluating effect an inert (NaClO4) versus oxidizable species (NaCl). In both conditions, five identified, desethyl-atrazine (DEA), hydroxyatrazine (ATZ-OH), desisopropyl-atrazine (DIA) desethyl-desisopropyl-atrazine (DEDIA). A degradation mechanism model describing hydroxyl radicals active contributions at ATZ also proposed. Intermediate evolution profiles suggest be considered series–parallel reaction system. Finally, energy requirement assessment carried out. highest (≅98%) achieved with NaCl = 0.08 M, J 60 A/m−2, EC 5.83 kWh m−3. Results highlight improved when (NaCl) present in solution. Moreover, addition energy-saving strategy. Collectively, technique efficiently treat polluted order meet needs recycling quality reduce resource consumption.

Atrazine, an herbicide used to control grassy and broadleaf weed, has become essential part of agricultural crop protection tools. It is widely sprayed on corn, sorghum sugar cane, with the attendant problems its residues in agri-food washing water. If ingested into humans, this residual atrazine can cause reproductive harm, developmental toxicity carcinogenicity. therefore important find clean economical degradation processes for atrazine. In recent years, many physical, chemical biological methods have been proposed remove from aquatic environment. This review introduces research works aqueous solutions by method classification. These are then compared their advantages, disadvantages, different pathways Moreover, existing toxicological experimental data metabolites summarized. Finally, concludes directions future major challenges be addressed.
