MODIFIED ACTIVATED CARBONS OBTAINED FROM VITICULTURE WASTE FOR MERCURY ADSORPTION
Main Article Content
Abstract
Mercury is one of the most toxic metals present in the environment. Among the proposed technologies to remove mercury, adsorption has been considered an economically feasible one. This contribution presents a comparative study of adsorption in column of three activated carbons obtained from waste of the viticulture industry (grape stalk, grape lex and grape marc), as adsorbents of mercury in liquid phase. The adsorbents were treated with carbon disulphide, to introduce sulphur onto the adsorbent surface, which has been reported as an element that favours the adsorption of mercury.
Adsorptions in column assays to entrap mercury were performed for all the activated carbons and the breakthrough curves were used to compare their performance.
The structural and textural parameters of the adsorbents, as well as the operation variables (pH and temperature) and their influence on the adsorption capacity of the solids were discussed.
