By the addition of an excess of silver nitrate solution and the determination of surplus silver ions with AAS, the chlorine content is thus determined indirectly.
采用加入过量的硝酸银溶液，用原子吸收分光光度法测量剩余的银离子，间接测量氯含量。

Chlorine ion did not interfere at up to 1200 fold excess. Iodine ion could be eliminated before the assay by bubbling nitrogen through the solution under mild oxidizing conditions.
