Abstract: This paper analyzes the factors affecting detection results and optimizes experiment conditions based on a new integrated intelligent instrument for evaluating rapidly scale inhibitor performance. The optimum conditions were as follows: 0.100mol/L sodium carbonate, 0.0126mol/L calcium chloride, keeping constant solution temperature within ±0.25℃ and detector cleaning procedure. In the given conditions, the evaluation results of PBTC, HEDP, ATMP etc showed that the method was perfect in stability and repeatability and could effectively meet the needs of the accurate and rapid evaluation of scale inhibitor performance.

摘要： 利用基于手工电导法的自制智能检测仪器，通过检测结果的影响因素分析和实验条件优选，给出实验室测量条件：0.100 mol/L Na₂CO₃、0.012 6 mol/L CaCl₂、溶液温度恒定在选定温度±0.25 ℃和测定池的清洗工序。在给定实验条件下，对PBTC、HEDP、ATMP等阻垢剂进行的评定结果表明：该方法具有比较理想的稳定性、重复性，能更好满足水处理剂生产企业和众多行业用户对药剂阻垢性能评定的需求。
