- Sulfate in various types of aqueous solutions such as soil‐water extracts, sewage effluents, irrigation water, and well water can be determined rapidly and accurately by a volumetric technique. The indirect method is based on the formation of the barium‐nitrochromeazo complex. Using a water‐acetone medium sharpens the end point and adding NH4F at low pH controls interferences.
