摘　　要：近年来,铍试剂Ⅲ(BeryllonⅢ)在分光光度法中已用于铍、铝、硼、钛、钒等的测定。由于该试剂在极谱分析上是良好的电活性物质并能与某些无机离子形成络合物吸附在滴汞电极上产生良好的吸附波,已用于铍、硼、钒等的测定。但用于镓的测定在上述两方面均未见过报导。In a buffer solution of pH5.5±0.2 the complex of gallium with beryllonM produces a well-defined polarographic adsorptive complex wave with peak potential at-0.47V.The height of the derivative peak is proportional to the concentration of gallium in the range of 0.005-0.8μg/ml.The electrode process of the adsorptive complex wave has been discussed.The method has been used to determine trace amounts of gallium in geochemical standard reference sam-mples.
