| Abstract: | The article researches the methods of extracting iodine compound from indium and thallium and absorptionmetric determination of indium and thallium from geological sample. This simple method has determined the minimum level of the compound avoiding the distraction of the coexisting ion making the determination of indium and thallium more sensitive. |
