摘要
阐述了折光率法与电导率法测定稀土废水中高浓度氯化铵的原理和方法。在恒温和低悬浮物浓度条件下,折光率与氯化铵质量浓度线性关系良好;当保持外界条件不变时,氯化铵质量浓度在5 000 mg/L^60 000 mg/L与电导率显著相关。经t检验,两种方法与银量法差异均不显著,且操作简单,准确快速,适用于水处理过程中的现场实时监测。
Determination of high-content Ammonia Chloride in the rare-earth wastewater where there is little suspended matter by conductometric and refractometric analysis is described, t test （compared with Silver nitrate titration） had been done. The two methods have the advantages of simpler operation accurate and quickness, so it is suitable for routine analysis of product in situation.
