Plastic products are used in almost all aspects of our daily life. Due to their low cost, portability, durability, and resistance degradation, these affecting the health environment biota on a global scale. Thus, removal mineralization microplastics is an important challenge 21st century. Advanced oxidation processes (AOPs) have recently been identified as viable treatment technique for tacklin...

Advanced oxidation processes (AOPs) have been reported as alternative ways for treating reverse osmosis (RO) concentrate which is the primary concern water reclamation plants. AOPs are known to oxidize recalcitrant organic compounds by a highly reactive and nonselective oxidant, hydroxyl radical (<sup>?</sup>OH). Researchers showed that such conventional Fenton, UV/H<sub>2<...

In the present work advanced oxidation process, photo-Fenton (UV/H2O2/Fe+2) system, for treatment of wastewater contaminated with oil was investigated. The reaction influenced by input concentration hydrogen peroxide H2O2, initial amount iron catalyst Fe+2, pH, temperature and in wastewater. removal efficiency system UV/ H2O2/Fe+2 at optimal conditions dosage (H2O2 = 400mg/L, Fe+2 40mg/L, pH=3,...

The mineralisation of remazol black B (RBB) was studied at concentrations ranging from 20-1000 mgL(-1). The work was aimed at investigating the Fenton-like peroxidation of RBB at a concentration typically obtained in Batik cottage industries. Other response parameters were degradation and colour removal efficiencies. The parameters that were measured included total organic carbon (TOC), chemica...

The hydroxyl radical (OH radical) formation rates from the photo-Fenton reaction in river and rain water samples were determined by using deferoxamine mesylate (DFOM), which makes a stable and strong complex with Fe(III), resulting in a suppression of the photo-Fenton reaction. The difference between the OH radical formation rates with and without added DFOM denotes the rate from the photo-Fent...

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...
