The mineralization of tetracycline by electrochemical advanced oxidation processes (EAOPs) as well the study toxicity its intermediates and degradation products are presented. Electro-Fenton (EF), anodic (AO), electro-Fenton coupled with (EF/AO) were used to degrade on carbon felt (cathode) a sub-stoichiometric titanium oxide (Ti4O7) layer deposited Ti (anode). As compared EF AO, EF/AO system r...

Small volumes (100 mL) of acidic aqueous solutions with 30-200 mg L TOC of the toxic azo dye Acid Red 1 (AR1) have been comparatively treated by various electrochemical advanced oxidation processes (EAOPs). The electrolytic system consisted of a BDD anode able to produce OH and an air-diffusion cathode that generated H2O2, which subsequently reacted with added Fe to yield additional OH from Fen...

This paper evaluates the degradation of two azo reactive dyes, C.I. Reactive Yellow 84 (RY84) and C.I. Reactive Red 120 (RR120) by photo-Fenton and Fenton-like oxidation. All experiments were performed on a laboratory scale set-up. The effects of different reaction parameters such as initial pH, contact time, effect of light and hydrogen peroxide concentrations on the oxidation of the dye aqueo...

Background & Aims of the Study: Pharmaceutical compounds have a variety of forms and applications. Specific amounts of toxic organic compounds in the process of their manufacturing and utilization cause environmental pollution problems. So, degradation and removal these compounds are necessary. The aim of this paper is the study photocatalytic degradation of ciprofloxacin drug in aqueous soluti...

The development of novel approaches to the remotion pharmaceuticals in wastewater is a subject concern due their effect on living beings and environment. Advanced oxidation processes use relevant catalysts are feasible treatment alternatives that require further development. suitable heterogeneous necessity. This work proposes synthesis an iron catalyst deep eutectic solvent (Fe-DES) composed c...

Ni-ethylenediaminetetraacetic acid (Ni-EDTA) poses serious threats to the ecological environment and human health, due its acute toxicity low biodegradability. The decomplexation efficiency of Ni-EDTA through conventional Fenton process has been constrained pH; thus, other appropriate approaches are required destroy stable chelate structure at a neutral pH. In this study, effect operating param...
