摘要
本文在查阅国内外文献的基础上，对氰化物测定中的前处理方法和干扰消除进行了简要综述。同时对氰离子选择电极法测定氰化物进行了研究，测定的ｐＨ应控制为１２－１３．检测下限为０．０３ｍｇ／ｌ。并用离子交换的方法分离阳离子，以ＰｂＣＯ＿３为沉淀剂分离Ｓ￣（２－）后，对废水样进行分析，效果良好。
Based on references listed listed in this paper,the pretreatment and elimination of interference have been reviewed sum-marily in determination of cyanide.And the determination. And the determination by ion-selective electrodes has studied. Its pH should be adjust-ed to 12-13, the limit of detection is 0.03mg/l. Satisfactory results were obtained for wastewater after separation by cation ex-Changer and from S￣(2-)by pptn. as pbs.
