摘要
本文基于氨三乙酸为活化剂,Mn(Ⅱ)对KIO_4氧化次甲基氯的催化效应,建立了一个测定超痕量Mn(Ⅱ)的新方法.本法的检出限为1×10^(-10)g/ml,测定范围为0～40ng/25ml,用于地下水中痕量Mn(Ⅱ)的测定,结果令人满意.
A catalytic Spectrophotomctric method for the determination of ultra-trace Mn(Ⅱ ) in ground water has been developed in this paper, The reaction of oxidation trimethyl chlorine with KIO4is catalysed by Mn(Ⅱ ), in the presence of nitrolotricetic acid as activator. The detection limit is 1 × 10-10g/ ml, The linear respondence is in the range of 0-40ng / 25ml. The proposed method has been applied to determine water samples with satisfactory results.
