متن کاملRecovery of Metals from Electroplating Wastes
Disposal of metal finishing wastes is one of the most critical industrial waste problems in the United States today. Recent legislation greatly restricts the discharge of most heavy metals to watercourses and future discharge regulations may further restrict their release to the environment. Furthermore, interest in developing possible methods for reclaiming metals from plating waste streams is...
متن کاملHeavy metals removal from electroplating wastewater by aminopropyl-Si MCM-41.
The potential of removing nickel and copper from industrial electroplating wastewaters by using mesoporous materials with MCM-41 type structure functionalised with different ratios of aminopropyl groups, namely Na50, Na25 and Na5, were evaluated. The synthesised solids sorbents obtained were characterised by X-ray diffraction, elemental chemical analysis and IR spectroscopy. In preliminary expe...
متن کاملRecovery and Concentration of Precious Metals from Strong Acidic Wastewater
Generally, trace precious metals remaining in wastewaters generated from the refining process of precious metals are not recovered, due to a relatively high processing cost as well as various technical problems. Recovery of precious metals from wastewaters is very important for the conservation of resources and the protection of environment. However, wastewaters containing a large amount of amm...
متن کاملSelective separation of chromium (III) from electroplating effluents by ion-exchange processes
This work reviews the application of the ion-exchange technology to treat industrial effluents containing heavy metals and presents results on the uptake of Cr (III) from aqueous solutions using the polyfunctional chelating exchange resin Diphonix. Some industrial samples of effluent collected in an electroplating industry were characterized in what respects metals, total suspended and dissolve...
