Re-evaluation of conventional wastewater treatment processes is paramount importance to improve the overall quality our aquatic environment. Electrochemical Advanced Oxidation Processes (EAOPs) are most promising alternative methods with application in facilities since situ electrogenerated oxidant agents degrade and mineralize a wide range water pollutants. Boron-doped diamond (BDD) technology...

Abstract The mechanism of oxidation and degradation effect phytate-modified biochar catalyzed persulfate on Ponceau 2R was investigated. Chemical-structural properties biochar, such as surface morphology oxygen-containing functional groups were characterized. results suggest that modified has better performance than unmodified the generated at 500 ? pyrolysis temperature can catalyze peroxymono...

In recent years, due to the abuse of pharmaceuticals and personal care products (PPCPs), many refractory trace organic compounds (TrOCs) have been transferred into natural water bodies, posing significant challenges environment. On other hand, advanced oxidation processes (AOPs) are cleaner more efficient than traditional biochemical degradation processes. Among them, combined ozone/persulfate ...

We report a novel transparent copper-based grid electrode fabricated by microcontact printing that offers high stability toward oxidation in air. Passivation is achieved using 2.5 nm thick layer of nickel buried just below the surface copper film from which etched. This approach to passivation retains advantages associated with lithography for fabrication very fast resist deposition and compati...

a new potassium persulfate redox system has been investigated for the graft polymerization of vinyl monomers. in this study potassium persulfate system was used for initiation the polymerization. graft polymerization of acrylonitrile (an) onto starch (sta) was carried out in aqueous solution using potassium persulfate (i) redox system. it was found that the percentage of grafting and rate of gr...
