Recovery of butyric acid, valeric acid, and caproic acid (BVC acids) from an aqueous waste stream using tributylphosphate (TBP) as an extractant

Abstract

The distribution coefficients, K_D, were measured for the extraction of butyric acid, valeric acid, and caproic acid with tributylphosphate from an aqueous waste stream. The measurements were also carried out in the presence of salts such as sodium sulphate and sodium chloride. The results presented are expected to aid process environmental engineers.
