Research on the Determination of Total Hardness in Drinking Water by Microscale Chemistry Experiment

摘要：

Total hardness is an important index to evaluate drinking water quality. Total hardness in drinking water was determined by micro titration and conventional titration seperately and parallel determination results of microscale chemical laboratory and constants experiment were compared. The results of micro titration were accurate and reliable. Microscale laboratory has such characteristics as obvious phenomena, saving reagents, fast analysis. So the cost was reduced and the innovative ability of students was improved by full compliance with the concept of green chemistry. Microscale laboratory is worth promoting.
