浊点萃取-火焰原子吸收法测定水中的痕量钴

摘要

The method was describe in detail using DDTC as complex agent to extract and preconcentrate Cobalt and optimize the experimental condition.This method was used to determine cobalt in water samples,and had been carried on the confirmation to this method reliability and the accuracy.%研究了以DDTC作为配位剂,浊点萃取预富集-火焰原子吸收法应用于水样中痕量的钴测定的实验方法;对实验条件进行了优化,用该方法对水样中的钴含量进行了测定,并对此方法的可靠性和精确性进行了验证。
