Diazinon pesticide and its metabolites have been identified in aquatic systems worldwide. It was related to toxicity for aquatic organisms, animals, and humans. Waters contaminated with such persistent insecticides should be treated with suitable treatment processes. In this research, Diazinon removal from aqueous solutions by the photo–Fenton–like process (UV/H2O2/Fe...

This work proposes an efficient combined treatment for the decontamination of a pesticide-containing wastewater resulting from phytopharmaceutical plastic containers washing, presenting a moderate organic load (COD=1662-1960 mg O₂ L⁻¹; DOC=513-696 mg C L⁻¹), with a high biodegradable organic carbon fraction (81%; BOD₅=1350-1600 mg O₂ L⁻¹) and a remaining recalcitrant organic carbon mainly due t...

The present work investigates the conjugation of flotation and photo-Fenton techniques on oil removal performance from oilfield produced water. The experiments were conducted in a column flotation and annular lamp reactor for induced air flotation and photodegradation steps, respectively. A nonionic surfactant was used as a flotation agent. The flotation experimental data were analyzed in terms...

Four phenylurea herbicides (isoproturon, chlortoluron, diuron and linuron) were dissolved in different water matrices in order to study their chemical degradation by using UV radiation, ozone and some advanced oxidation processes (UV/H2O2, O3/H2O2, Fenton reagent and the photoFenton system). The waters used were: ultra-pure water, a commercial mineral water, a groundwater and a surface water ta...

The generation of disinfection by-products during water treatment can be controlled by reducing the levels of precursor species prior to the chlorination step. The Natural Organic Matter (NOM) is the principal organic precursor and conventional removal of pollutants such as coagulation, flocculation and filtration do not guarantee the total NOM removal. In this study the degradation of NOM mode...

Among various advanced oxidation processes, coupled photocatalysis and heterogeneous Fenton-like catalysis (known as photo-Fenton-like catalysis) to generate highly reactive species for environmental remediation has attracted wide interests. As an emerging metal-free photocatalyst, graphitic carbon nitride (g-C3N4, CN) been recently recognized a promising candidate catalyze robustly reactions w...

and cause health and environmental effects. this study investigates the optimization of the parameters affecting the advanced oxidation process fenton for improving toc removal from aqueous solution includes amoxicillin antibiotic by using taguchi experimental design. methods: in this study for evaluation the effect of factors and determination optimal conditions to removal toc by fenton proces...

The objective of this study is to evaluate the turbidity generated during Fenton photo-reaction applied oxidation waters containing carbamazepine as a function factors such pH, H2O2 concentration and catalyst dosage. results let establish degradation pathways main decomposition byproducts. It found that pH affects water. Working between = 2.0 2.5, under 1 NTU due fact iron, added catalyst, in f...
