摘要
Abstract
In the test of standard addition for water quality, the influence of standard-added part on volume of sample solution is easily overlooked, causing deviation in the calculation of recovery rate of standard addition. In view of the definition of recovery rate of standard addition and the change in each volume parameter in the actual detection, the recovery rate calculation by using different water quality analysis methods is discussed, and the calculation differences between determining volume after standard addition and standard addition after determining volume are studied. The analysis results show that the influence of determining volume after standard addition on sample solution volume can be neglected;on the contrary, the influence cannot be neglected.关键词
