Abstract

The WET PROCESS PHOSPHORIC ACID (WPA) is used to produce fertilizers and alimentary supplies for cattle. In each of these applications, the impurities contained in acid must be in standard range. In this paper PURIFICATION of WPA by SOLVENT EXTRACTION is performed and the effect of the mass ratio of solvent to feed on extraction efficiency is studied. The working solvents are METHYL ISO BUTYL KETONE (MIBK), ISO AMYL ALCOHOL (IAA) and the mixture of them. The results show that the IAA is better than other solvents in extraction of WPA. This solvent can extract 82.2% of acid after two extraction stages but MIBK can extract only 73.5% of acid after three extraction stages. For all of these solvents, the Pb and Cd concentrations go down to trace. The experimental results show that the maximum separation of Mg with MIBK is 87.5% which occurs at the mass ratio of solvent to feed eual to 4. In the case of IAA solvent the percent is 91.7% and the ratio is 8.
