This standard specifies the barium sulfate turbidimetric method for the determination of sulfate in drinking water and its source water. This method is applicable to the determination of soluble sulfate in drinking water and its source water. The minimum detection quality of this method is 0.25 mg, if a 50mL water sample is taken for determination, the minimum detection quality concentration is 5.0 mg/L. This method is suitable for the determination of water samples below 40 mg/L sulfate. Stirring speed, time, temperature and reagent addition methods can all affect the measurement results of turbidimetry, so it is required to strictly control the consistency of operating conditions.
