Synthesis swelling rheological and Metal adsorption behaviour of Polysodium acrylate hydrogels

Abstract

Many techniques have been employed to recover both toxic and newlineprecious metals from waste PCB The conventional methods such as newlinepyrometallurgical hydrometallurgical biometallurgical and electro deposition newlinetechniques suffer in technical and economic feasibility Apart from technical newlineand economical infeasibility most of the conventional processes involve newlinecombustion pyrolysis and hydration which have proven dangerous as they newlinegenerate lot of environmental pollution Humans are often exposed to large newlineamounts of toxic gases which are extremely harmful newlineRecovery of both toxic and precious metals from waste PCB is an newlineinteresting subject not only from the point of environmental aspect but also newlinefrom the recovery of precious metals The problems associated with newlineconventional methods and the value of the precious metals from waste PCB newlinemotivated us to develop a new method for the recovery of both toxic and newlineprecious metals from waste P newline newline
