Abstract
Objective: To understand the concentration trend and dispersion degree of sulfate content in 140 samples of drinking water in dry season in Xingyi City. Methods: The domestic drinking water in the area of Xingyi City was divided into water plant water, water plant end water and small water cellar water. The residual chlorine was detected at the site, and the preserved reagent was added to the water and sent to the laboratory to test the sulfate content according to the ion chromatography method (GB/T5750.5-2006 3.2). The test results were statistically analyzed using the Statistical Software for Physical and Chemical Test Data and IBM SPSS Statistics22 statistical software. Results: The median of 70 samples of factory water and terminal water was 24.63 mg/L, and that in 70 samples of small cellar water was 28.56 mg/L; the variation coefficient of 70 samples of factory water and tip water is 104.788%, and that of 70 samples of small cellar water is 61.012%. Conclusion: The sulfate test results of 140 samples of drinking water in Xingyi City in dry season conform to the provisions of GB5749-2006.
