Abstract
The ultimate usage of phosphoric acid is declared in food and fertilizers industries. Therefore, purification of commercial phosphoric from their serious contaminates is needed. Uranium and organic pollutants are of the most common impurities in such acid. In this study, removal of these two contaminants via adsorption was carried out onto freshly made bio-carbon that is modified by co-loading of metallic sites. Acquired results revealed successful elimination of 60 and 94% for organic matter and uranium species respectively from 23.5% P2O5 phosphoric acid using metalized activated bio-char according to the following conditions; shaking time of 120 min and sorbent dose of 20 g/L. It could be also observed that the adsorption process is applicable for both high strength and diluted phosphoric acid.
