The toxic cyanides in gold cyanide residues produced the cyanidation process of extraction threaten environmental safety and inhibit recovery valuable metals. In this study, removal through persulfate-advanced oxidation was investigated, heat activation ultrasonic were tested for removal. results showed that residue could be removed by 2.0 wt.% potassium persulfate at pH 10.0 after 60 min react...

An experimental study on 4-chlorophenol (4-CP) degradation in aqueous solutions by advanced oxidation process photo-Fenton type is presented. The efficiency of the oxidation process is determined by the very high oxidative potential of the OH. radicals generated by catalytic and photo-catalytic processes. The presence of the inorganic species inside the reaction medium influences the rate of th...

In this work, for eliminating the (RR1346), considered to be a waste in wastewater from dye industries electrochemical advanced oxidation process has been used. Graphene oxide coated carbon cloth (GO/CC) and Fe3O4 /GO coated carbon cloth (Fe3O4/GO/CC) electrodes has been fabricated by synthesized GO and Fe3O4 nanoparticles. Characteristic properties such as surface morphology as the main reason...

background: electrochemical methods, as one of the advanced oxidation processes (aops), have recently been applied to remove different contaminants from water and wastewater. this study compares the performance of anodic oxidation (ao) and electro-fenton (ef) methods on waste sludge treatment. methods: this experimental study was performed on real sludge and the effect of operating parameters s...

Application of plasma oxidation for removal pharmaceuticals in urine was assessed and compared to a traditional advanced process.
