| Abstract: | In a pH2.4 buffer solution of HCl-NHUAc containing 0.03%a, a'-dipyridyl, l%ammo-nium rhodanide, 0.00l%tetraphenylarsinium chloride, a new sensitive adsorptive complex wave of indium has been obtained by single-sweep polarography. The detection limit is 0.2ng/ml. The linear relationship is obtained between peak height and concentration of indium in the range of 0.0004-lug/ml. The wavehas been proved to be a polarographic adsorptive complex wave. The method has been applied to determine the trace indium in geological samples with satisfactory results. |
