The Research of Extracting Hippuric Acid from Breeding Wastewater

Abstract:

Hippuric acid as an important raw material used to synthesize medication and coloring matter, abound in urine of much animal, especially in cattle. Hippuric acid usually is letted into river and soil with the urine. But as its chemical stability, hippuric acid couldn’t be decomposed easily and pollute the environment. This research finds effectively liquid membrane to treat with such waste water such as breeding wastewater that contains high hippuric acid. In our study, the best liquid membrane was found by searching what and how much surface active agents and carrier are suitable, pH of out-water of the liquid membrane and concentration of NaOH in the in-water of liquid membrane. As the outcome shown, the best prescription is surface active agent T-151(2% mass fraction), liquid carrier TBP( 4% mass fraction), pH of out-water 2.0, concentration of NaOH in the in-water 0.50mol/L. Under the condition, extraction rate of hippuric acid from breeding wastewater can reach more than 98% during 9min.
