Use of dialysis to limit interferences in the turbidimetric determination of sulfate


An automated barium sulfate (BaSO4) turbidimetric method for the determination of sulfate (SO4) in 0.002M CaCl2 soil extracts is presented which utilizes a dialysis stage to remove interferences. Dialysis was effective in removing particulates and organic coloration which caused overestimation of the SO4 concentration, producing results comparable to those achieved by ion chromatography
