The process of separating gold, silver and / or palladium from copper and other contaminated metals, using an appropriate filter membrane, preferably a nanofilter, to form a bunker containing most of the multivalent metal cyanide compounds. The filter is equipped with an electric charge, which is...
the evaluation of biochemical biomarker metallothionein may be useful in assessing metal exposure and the prediction of potential detrimental effects induced by metal contamination. There are some methods for the determination of metallothioneins including spectrophotometric method, electrochemical methods, chromat...
