Abstract

Copper and Chromium are hazardous heavy metals which are present in most industrial effluent streams which, if not removed, are potential threats to both environment and health of living organisms. So the removal of these metals has become rather imperative. So various techniques have come up over the last few decades but most of them are energy and cost intensive. Adsorption is a technique which has quite less energy requirements and found to be economic. In the current study, selective adsorption of these metals from the aqueous solution using activated charcoal adsorbent has been analyzed. Selective batch adsorption of the metals is studied with two variables (adsorbent dosage, adsorbate dosage), keeping one constant at a time. The results showed that selective adsorption of Cu(II) from the solution is possible using the adsorbent considered.
