Abstract

In the present study, Valeric acid extraction in Aqueous two-phase systems Polyethylene glycol with a molecular weight of 4000 g / mol and sodium dihydrogen phosphate (NaH2PO4), di-potassium hydrogen phosphate (K2HPO4), and di-ammonium hydrogen phosphate ((NH4) 2HPO4) At temperatures of 35 and 25 degrees Celsius. The effect of salt type and its concentration, temperature, and pH on the formation of an aqueous two-phase system were studied. It was observed that with increasing salt concentration, the Distribution Coefficient and the percentage of extraction of Valeric acid decreased. The salt type has an important effect on the extraction of Valeric acid so that the sodium salt of dihydrogen phosphate has a higher Distribution Coefficient(%44) than the other two salts. Also, the extraction of Valeric acid in a lower temperature(Temperature is 25 ° C) environment resulted in a better result. In this study, pH values of 5, 6, 7, 8 were investigated and it was observed that the Distribution Coefficient of Valric acid would be higher(pH = 5), and the maximum percentage of extraction of Valeric acid for the best salt (sodium dihydrogen phosphate) was obtained up to 50%.
