The quality of ferric sulfate solution and the content of ferric sulfate in the solution were evaluated. The test methods of total iron content and reducing substance content refer to GB / t14591-2016 water treatment agent polyferric sulfate. Using the single factor experimental method, four main influencing factors, reaction temperature, total iron concentration, solution pH value and reaction time, were selected to explore and analyze the influencing factors of the preparation of polymeric ferric sulfate. The prepared nano polymeric ferric sulfate particles were analyzed by infrared spectroscopy and X-ray diffraction. The data set contains 7422 data and 6 groups of data.
