催化动力学法测定微量Co~(2+)已有报道,方法灵敏度一般在10~(-6)～10~(-10g)数量级,多数用于测定水、血液和高纯物质中的Co~(2+),而测定中药內的痕量CO~(2+)还未见报道。本文研究了氨水介质中Co~(2+)催化二苯偶氮酰肼氧化褪色的新指示反应及动力学条
The catalytic kinetic method for the determination of trace Co 2+ has been reported. The sensitivity of the method is generally in the order of 10 -6 to 10 -10 g. Most of them are used for the determination of Co 2+ in water, blood and high- (2+), while the determination of trace amounts of CO 2 in traditional Chinese medicine has not been reported yet. In this paper, the new indication reaction and kinetic band of Co ~ (2+) -catalyzed oxidation diphenyl azide hydrazide oxidation in aqueous media
