The degradation of chlorpyrifos in water by Fenton (H2O2/Fe 2+) and solar photo-Fenton (H2O2/Fe 2+/solar light) processes was investigated. A laboratory-scale reactor was designed to evaluate and select the optimal oxidation condition. The degradation rate is strongly dependent on pH, temperature, H2O2 dosing rate, and initial concentrations of the insecticide and Fe 2+. The kinetics of organic...

this study investigates the degradation of sodium dodecylbenzenesulfonate (sdbs) in aqueous solution by the fenton-like oxidation process. the effects of different parameters such as concentrations of ferric chloride and hydrogen peroxide, ph and reaction time on the sdbs removal and chemical oxygen demand (cod) reduction were evaluated. response surface methodology (rsm) with central composite...

Abstract Heterogeneous photo-electro-Fenton oxidation (hPEF) is known to be a robust technique, which can employed for promoting organic degradation. This paper describes an environmentally friendly approach with the combination of photocatalysis and electrocatalysis in less acidic pH, aiming achieve faster mineralization pharmaceutical micropollutant without adding any external oxidants. TiO 2...

The overuse of herbicides has posed a threat to human health and the aquatic environment via DNA mutations antibiotic gene resistance. Carbon-based cathodic electrochemical advanced oxidation evolved as promising technology for herbicide degradation by generating hydroxyl radicals (•OH). However, conventional electro-Fenton process relies on interaction multiple species that adds system complex...

In recent years, the removal of pharmaceutical and personal care products (PPCPs) from aqueous solutions has been gaining a lot attention researchers throughout world. This is particularly due to concern about their potential hazards toxicities, as they are classified emerging contaminants. Thus, there an increasing need investigate technologies for PPCPs at deeper more holistic level. review a...

In this work, the degradation of 2-chloro-4,6-diamino-1,3,5-triazine in aqueous solutions by photo-Fenton process has been investigated. The preliminary results have shown that the degradation of 2-chloro-4,6-diamino-1,3,5-triazine by photo-Fenton process is more rapid and more effective than Fenton and UV/H2O2 processes. The effects of certain experimental parameters on kinetics and efficiency...

With the development of industry and agriculture, increasingly serious problems environmental pollution water quality deterioration that affect human health need to be solved. Materials containing both Fe Mn, two most abundant metal elements, have been widely used for wastewater decontamination since they are nontoxic, low-cost, easy prepare, highly efficient. This review systematically summari...

This study reports the removal of amoxicillin (AMX) in aqueous media using electro-Fenton process presence a graphite cathode recovered from used batteries. The impact relevant parameters on process, namely applied current intensity, temperature, initial concentration AMX and ferrous ions were investigated. results showed that optimal values were: I = 600 mA, T 25 °C, [AMX] 0 0.082 mmol·L ?1 [F...
