间接原子吸收法测微量氯

Indirect Determination of Microamount Chloride by Atomic Absorption Spectrophotometry

含乙醇试液中加入过量硝酸银标准溶液，根据过剩银的原子吸收信号，用作图法或计算法间接测得自来水中微量氯，回收率在９７％～１０４％之间．

The indirect AAS determination of microamount chloride in running water.After the addition of standard silver nitrate solution,the content of chloride can be found with the absorption signal of the residual silver in solution. The recoveries 90%～ 104%.
