Among the various existing metals, zinc and copper are predominant metals in several effluents from industries such as electroplating, plastics production mining. Technical methods have been applied treatment of containing including chemical removal, adsorption, ion exchange, membrane technologies electrochemistry. However, it is necessary to develop that minimize costs increase quality while r...

Electrochemical methods and processes have been applied for many years in environmental applications such as water/wastewater treatment, recovery of metals, electroplating and qualitative/quantitative analysis in various aqueous media. Among these processes, electro‐ coagulation (EC) has gained many interest due to providing simple, reliable and cost effective operation for the treatment of was...

Electroplating sludge (ES) is currently disposed in landfills and, because of its heavy metal content, poses serious threats to the environment and human health. However, ES might have potential use as colouring agent due high concentration chromium nickel. Thus, present work aims at studying effect incorporation into stoneware bodies. The influence on final characteristics fired samples, amoun...

The solidified landfill disposal of hazardous solid waste such as electroplating sludge in arid/semi-arid areas has potential risks and hazards. In this study, the electrochemical method was used to destroy structures metal complexes release ions so that organics were removed by direct mineralization anode while recovered cathode. A SnO2/Ti electrode during electrolysis process. effect differen...

Abstract Herein, a KFeS 2 whisker was formed in mass production at low temperature, with waste cold-rolling sludge as Fe source, which exhibited good performance the removal of Zn/Ni from real electroplating effluent. At laboratory scale, generated 80 °C by hydrothermal method, and grew radially extension reaction time. This method applied pilot where similar also produced residual brownish sup...

Speciation of copper in the electrokinetic treatments of an industrial sludge was studied by in situ extended X-ray absorption fine structural (EXAFS) and X-ray absorption near-edge structural (XANES) spectroscopies in the present work. The least-square fits (LSF) of the XANES spectra indicated that the main copper species in the sludge were Cu(NO)(3) (82%) and adsorbed copper (Cu/SiO(2)) (17%)...
