动力学光度法测定痕量钴的研究
DYNAMICS KINETICS SPECTROPHOTOMETRIC DETERMINATION OF TRACE COBALT SYSTEM OF COBALT?
【摘要】 本文研究了硼砂—氢氧化钠介质中(pH= 11 .0) ,钴? 催化过氧化氢氧化桑色素的反应,建立了动力光度法测定痕量钴的新方法.方法灵敏度高,线性范围0 ~0 .1 μg·ml-1 ,检出限为0 .2 ×10 - 10 g·ml- 1 .实测了含钴药品中Co ? 含量,结果令人满意.
【Abstract】 A new dynamics kinetics spectrophotomtic method for the determination of trace Cobalt has been studied.The mothod is based on the dynamics kinetics effect of Cobalt ? of morin by hydrogen proxide in the Na 2B 4O 7 NaOH(pH=11.0) medium.The linear range is 0~0.1 μg·ml -1 .The detection limit of Cobalt ? is 0.2×10 -1 g·ml -1 .The method has been applied to the determination of Cobalt in medicine with satistactory result.
