摘　　要：本工作以Ｃｌ￣－与过量Ａｇ￣＋生成ＡｇＣｌ沉淀反应为基础。较详细地探讨了各种强电解质作为絮凝剂对ＡｇＣｌ沉淀的影响，确定了反应的条件，从而提出了一个测定水中Ｃｌ￣－的间接原子吸收法，Ｃｌ￣－浓度在０－５０ｕｇ／１０ｍｌ范围呈线性，用建立的方法测定自来水中Ｃｌ￣－，再现性与准确度俱佳，用本法测定废水中Ｃｌ￣－的结果与经典的比浊法，和高子色谱法的结果相符。asek on the reaction of AgCl precipitation from Cl￣- with excess Ag￣+,the effects of several strong electrolytes ascoagulant agents on AgCl precipitation were studied in detail,reaction conditions were determined and then an indirect AAS de-termination of chloride in water is propbeed. The concentration of chloride in the range of0～50ug/10ml is linear.The proposedmethod used to determine micro chloride in tap water has good repreducibility and accuracy.As compared with classic turbidime-try and ion chromagraphy,it achieves the same results for determining Cl￣- in wastewater.
