A method is proposed for the extraction and separation of trivalent gallium, indium and thallium from their corresponding aqueous solutions at 65 u0003! with 2, 6-bis-(1’-phenyl-3’-methyl-5’-oxopyrazole-4’) pyridineacyl (H2PMBPPor H2A) using molten paraffin wax as a diluent. The values of pH1/2for extraction of gallium, indium and thallium are 2.62,4.32 and 4.93, respectively. Gallium can be extracted by H2PMBPP at a lower acid medium. The effect of solvent and the composition of the extracted species are reported. And the thermodynamic data of the extraction are also obtained.
