in the last twenty years, due to a number of natural and anthropogenic reasons, many water sources have become poorer in quality with respect to micropollutants. an example of a micropollutant that needs to be removed is the chlorophenoxypropionic herbicide mecoprop (mcpp). mcpp is one of the nine pesticides used as an indicator to monitor pesticide concentrations in rivers because it is freque...

the saline tannery wastewater also contains the high concentration of organic materials and various chemical compounds like lime, sodium sulfite, sulfate ammonium, sodium chloride, disinfections, vegetable tannins, salts of chromium and chloride. in recent years different applications of advanced oxidation processes (aops) are applied to remove organic loading (cod) from wastewater. advanced ox...

Early research on the Fenton reaction was mainly focused on organic synthesis, enzymatic reactions and the cell damage mechanism [2]. It was noted that in the presence of a catalyst, H2O2 can be efficiently decomposed to generate oxidative active substances with strong oxidizing power, and degrade a variety...

The Fenton reaction is the most widely used advanced oxidation process (AOP) for wastewater treatment. This study reports on the use of pyrite nanoparticles and microparticles as Fenton reagents for the oxidative degradation of copper phthalocyanine (CuPc) as a representative contaminant. Upon oxidative dissolution in water, pyrite (FeS2) particles can generate H2O2 at their surface while simul...

Advanced oxidation processes such as Fenton reagent generates highly reactive hydroxyl free radicals to oxidize various compounds in the water and wastewater. The efficiency of different Fenton-related oxidative processes such as Fenton, solar-Fenton, UV-Fenton and Fenton reactions in different batch reactors was examined using benzene as pollutant in aqueous solutions. A batch study was conduc...

Pyrite ash (PA) is created by burning pyrite in the chemical production of sulphuric acid. The high concentration of iron oxide, mostly hematite, present in pyrite ash, gives the basis for its application as a source of catalytic iron in a modified Fenton process for anthraquinone dye reactive blue 4 (RB4) degradation. The effect of various operating variables such as catalyst and oxidant conce...

this study aimed to explore concentration of a low grade sulfide-oxide lead-zinc sample containing 2.3% pb, 1.91% zn taken from changarzeh mine, south natanz, iran. the effects of different parameters such as type and dosage of collector, milling retention time, dosage of sodium sulfur and its preparation time, application of sodium silicate, ph and solid content were investigated in relation t...
