Effects of process factors on performances of liquid membrane-based transfer of indole-3-acetic acid.

ABSTRACT: The paper has aimed at studying the transfer of indole 3-acetic acid (IAA) from a feed aqueous solution to a stripping aqueous solution of NaOH using a chloroform bulk liquid membrane and trioctylamine (TOA) as a ligand (L). Initial molar concentrations of IAA in the feed phase, c_IAA,F0 (10^-4-10^-3 kmol/m³), of TOA in the membrane phase, c_L,M0 (10^-2 and 10^-1 kmol/m³), and of NaOH in the stripping phase, c_NaOH,S0 (10^-2 and 1 kmol/m³), were selected as process factors. Their effects on the final values of IAA concentration in the feed phase (c_IAA,Ff) and stripping solution (c_IAA,Sf), extraction efficiency (E_F), distribution coefficient (K
