Recovery of carboxylic acids, C2C6, from an aqueous waste stream using tributylphosphate (TBP): Effect of presence of inorganic acids and their sodium salts
Extraction of carboxylic acids, C2C6, was carried out with tributylphosphate (TBP) from an aqueous waste stream at pH = 2, 2.5, and at as such pH taken from an environmental process engineering point of view. The effect of the presence of H2SO4 and HCl on the distribution coefficients for C2C6 carboxylic acids was investigated. The measurements were also carried out in the presence of inorganic salts such as Na2SO4 and NaCl.
