摘要
根据苯并三氮唑和铜 (Ⅱ )能生成沉淀化合物的反应 ,分别研究了用苯并三氮唑和铜作沉淀剂 ,利用比浊法进行铜 (Ⅱ )和苯并三氮唑的相互测定 ,测定线性范围分别为 0 2～ 12mg/L和 2 4～ 2 1 6mg/L .该法所用仪器简单 ,操作简便 ,适宜于生产厂家和应用单位使用 .用该方法测定了内燃机车冷却水中的苯并三氮唑和糖精钠厂排放的废水中铜的含量 ,结果与电位滴定法及原子吸收法相吻合 .
This paper proposes a simple and convenient method of determinations of copper and benzotriazole with turbidimetry based on that copper(Ⅱ) that reacts with benzotriazole to form precipitation in the sodium acetate solution. The calibration graph is linear over the range of 60?μg～540?μg/25mL BTA and 5～300?μg/25?mL copper. The proposed method has been used to determine benzotriazole in cooling water and copper in waste with satisfactory results.
