Determination of Total Hardness in Drinking Water by Microscale Chemistry Experiment

摘要

Total hardness is one of important index to evaluate drinking water quality. The determination method of total hardness in the drinking water using the micro titration has introduced, and also has compared the obtaining results by the microburette and by the routine analysis. The relative standard deviation is far less than 2.0%. There is no obvious difference in the results. F examination and t examination are all in the appropriate scope.
