The operation links of water quality testing should eliminate the interference factors to minimize the system error. In this work, water sample proofreading and data analysis are conducted using EDTA standard sample in different power plant laboratories, to test the systematic error of the experimental operation link and put forward targeted solutions, in order to provide accurate and reliable experimental data for water quality supervision and management.
