| 摘 要： | 介绍了质量滴定分析法,通过质量滴定法对Hg(NO3)2和EDTA滴定液浓度的标定及对CaCl2、MgCl2和LiCl样品溶液浓度的测定,以及测定结果与基准称重法和重量分析法浓度测定结果相比较,验证了质量滴定法测定的准确性和精度,获得了相对偏差小于0.11%的一致结果。结果表明,溶液离子浓度的测定可用质量滴定法替代容量法和重量法。

| Abstract: | This paper describes the mass titration method,the concentrations of the Hg(NO3)2 and EDTA titrant solutions were calibrated and the concentrations of CaCl2,MgCl2 and LiCl solutions were measured by the method,the measured results were compared with benchmark weighing method and grayimetric method.It verifies that the accuracy and precision the mass titration is excellent and the relative deviation is less than 0.11%.The results show that the mass titration method can replace volumetric titration and gravim... |
