In this study, the heterogeneous Fenton-like degradation of Reactive Red 141 (RR141) in water was investigated over iron containing ZSM-5 zeolite (Si/Al = 42) prepared by ion-exchange (FeZSM-5 (42)). The catalyst was characterized by XRD, SEM, FTIR, TPR, and ICP-AES measurements. The effects of the initial concentrations of the dye and H2O2, the initial pH of the solution, catalyst loading, and...

Cavitation damage to membranes is a major barrier for developing an ultrasound (US)-assisted membrane water treatment process. In this study, US was integrated heterogeneous Fenton reactor the of pharmaceutical-containing with aims i) fouling control, ii) enhancement oxidation. order prevent damages due cavitation, stable and violent cavitation regions were identified by quantification analysis...

Background: Mitoxantrone (MXT) is a drug for cancer therapy and a hazardous pharmaceutical to the environment which must be removed from contaminated waste streams. In this work, the removal of MXT by the electro-Fenton process over heterogeneous and homogenous catalysts is reported. Methods: The effects of the operational conditions (reaction medium pH, catalyst concentration and utilized cur...

Herbicides have been largely utilized during the last decades to maintain quality and quantity of agricultural crop, ensuring need an increasing world food production. However, these synthetic organics are highly biorecalcitrant stable at mild conditions cannot be effectively destroyed in conventional wastewater treatment facilities. Among advanced oxidation processes used remove herbicides, el...
