摘要: 依来铬蓝黑B是一种金属指示剂[1],在pH1.95~12.20的Britton-Robinson缓冲溶液中产生一良好的还原波[2]。在氨性缓冲溶液中,当溶液的pH在9.5~11.3时,依来铬蓝黑B也产生一明晰波。

Abstract: The polarographic behaviour of Eriochrome Biue Black B and its complex with magnesium ion was investigated. The experimental data showed that the complex of magnsium ion with the dye exists in ratio 1:1.The apparent stability constants under different experimental conditions were calculated from the heights of polarographie waves.
