| 摘 要： | 针对EDTA滴定法测定水中总硬度(简称"标准法")时,存在的缓冲溶液配制繁琐、耗时长的问题,提出了缓冲溶液配制的改进方法(简称"改进法").改进法很好地克服了标准法的不足.通过地表水、地下水以及总硬度标准样品的比对测定,两法测定结果无显著差异.

| Abstract: | In determination of total hardness of water with EDTA titration, preparation of buffer solution is tedious and time-consuming. The proposed method overcame the deficiencies of the standard method. By measuring the total hardness in surface water, groundwater and standard samples using the standard method and the improved method, the results had no significant differences. |
