“钙、镁含量及水的总硬度测定”实验的改进

Improvement of the Experiment 'the determination of calcium and Magnesium content and total water hardness'

在钙、镁含量及水的总硬度测定实验中,研究了钙离子含量测定的主要影响因素及其消除方法。通过实验,论证了改进后的方法的有效性和实用性。采用本方法测定标准溶液及样品溶液中钙离子含量均获得满意结果。

In the experiment of calcium and magnesium content and total water hardness.Determination of calcium ion influence the process of interfering elements and the elimination method of in-depth discussion.Through experiments demonstrate the method is validity and usefulness.It＇s satisfactory results that determination of standard and the calcium content of the samples by the method.
