AbstractReactive extraction of gallic acid (GA) from aqueous solution was studied using extractant TOA and Aliquat 336 in hexanol and a comparative analysis were made for optimum extractant-diluent system with two factor central composite design. The model equations were developed using 13 experimentations, each with TOA and Aliquat 336. TOA and Aliquat 336 gave antagonistic and synergistic effects respectively for extraction of GA. The optimum conditions were observed as CTOA= 8.6 %, CGA0= 2.9 g/L and CALQ= 33.2 %, CGA0= 3 g/L with experimental extraction of 92.2 % and 96.5 % respectively. Lesser TOA and its non-toxicity for extraction of GA as compared to Aliquat 336 suggest TOA as better candidate in the prevailing conditions.
