本文将钼催化过氧化氢氧化硫代硫酸钠的反应与鲁米诺-H_2O_2化学发光反应相偶合,建立了痕量钼的无机偶合反应化学发光分析法。此方法的检出限是1.2×10~(-10)g/ml钼,相对标准偏差为2.7％(对5×10~(-9)g/ml钼11次测定),工作曲线的线性范围为1×10~(-9)～1×10~(-3)g/ml。此法巴成功地用于天然水中痕量钼的测定。
In this paper, the reaction of molybdenum-catalyzed oxidation of sodium thiosulfate with hydrogen peroxide was coupled with the luminol-H 2 O 2 chemiluminescence reaction, and a trace molybdenum coupling reaction chemiluminescence method was established. The detection limit of this method was 1.2 × 10 -10 g / ml molybdenum with a relative standard deviation of 2.7% (11 times for 5 × 10 -9 mol / mol molybdenum). The linear range of the working curve Is 1 × 10 ~ (-9) ~ 1 × 10 ~ (-3) g / ml. This FABA successfully used in the determination of trace amounts of molybdenum in water.
