【摘要】 本文以Mo（Ⅵ）-Oxine-KClO₃为体系,提出了2.5次微分极谱直接吸附测定痕量钼的新方法。催化电流的2.5次微分与钼浓度呈良好线性关系。恒速搅拌吸附富集3分钟,检出限达0.01ng/ml。20种不同金属离子对0.04μg/20ml钼在一定范围不发生干扰,应用于自来水、池塘水、井水、头发和血样中钼的分析,取得满意结果。同时测定了吸附配合物的组成更多还原

【Abstract】 In the 1.2×10^-3M Oxine, 0.01MKC10₃ and PH 2.7 supporting electroly te, Mo-Oxine complex has been shown to adsorb onto the hanging mercury drop electrode, and the reduction processes can be catalyzed by KC10₃. This property forms the basis of a sensitive electroanalytical chemistry technique by which trace molybdenum in Waters and Biological Materials can be determined adsorptively. The solution is not deaerated by purging with N₂ or Ar gas. The calibration curve is linear in the range from 0.4——20ng/ml, the limit of detection lies at 0.01 ng/ml after 3 min stirred collection. The composition of complex has been determined as Mo: Oxine= 1: 2.更多还原
