Recovery of Fumaric acid from Aqueous Solution Using Laboratory Prepared Nontoxic Diluent

Abstract

The present work was done to check the ability of three laboratory-modified nontoxic diluents (made from sunflower, rice bran, & Sesame oil) for the extraction of fumaric acid (dicarboxylic acid) with Tri-n-octyl amine as an extractant. Physical extraction studies with fumaric acid showed that the three modified diluents are incapable of extracting fumaric acid The most effective Tri-n-Octylamine (TOA) extractant was dissolved in the three modified diluents (made from sunflower, rice bran, Sesame oil). Extraction efficiency increased with the increase in the percentage (V/V) of Tri-n-Octylamine (TOA) indicating a prominent role of the extractant. The extraction efficiency of 30% Tri-n-Octylamine (TOA) inall the 3 modified oils (diluent) is nearly 90%. The effect of higher percentages of Tri-n-Octylamine (TOA) extractant on extraction efficiency was also studied but the marginal increase in the extraction efficiency was found for all the three laboratory-modified oils.
