摘要：A New turbidimetric method for the determination of sulphate in brackish waters is described. A suspension of barium sulphate is product in an acidified medium of glycerine d-glucose solution by the addition of barium chloride solution and the turbidity measured with the help of Bausch & Lomb Spectronic '20' Colorimeter. Concentrations upto 160 ppm of sulphate, mate ions do not interfere, nor do Cu/Sup2+, Fe/Sup3+, Co/Sup2+, Ni/Sup2+, and Cr/Sup3+. The method has been applied to the determination of sulphate in desert soils as well.
