Abstract
1) A simple method for sulfate microdetermination was established. Sulfate is precipitated as barium sulfate; then the excess of barium is precipitated as barium chromate. Finally the excess of chromate is estimated in alkaline solution with a spectophotometer at 375 mμ. 2) This method is able to be applied to sulfate solution containing sulfate sulfur in the range 10–300γ. (30–900γ as SO42−) 3) This method was successfully applied to the estimation of inorganic sulfate such as that in rain water and organic sulfate such as chondroitinsulfate, charoninsulfate, ethyl sulfate and p-nitro-phenyl sulfate.
