An indirect spectrophotometric method for the determination of sulfate using barium nitranilate has been investigated. The analytical procedure is as follows: Add 30 mg of barium nitranilate to 5 ml of ethanolic solution (1 + 10) containing sulfate (525 μg) in a 10-ml stopped centrifuge tube. Shake for 5 min with mechanical shaker, and centrifuge the precipitate for 10 min at 300 rpm. Measure the absorbance of the supernatant liquid at 300 nm with a 1-cm quartz cell against a reagent blank. Beer's law holds and the present method showed good reproducibility of relative standard deviation of 1.1 %, and the molar absorptivity for sulfate is 1.72 × 104 1mol-1 cm-1. Phosphate, thiosulfate, arsenate, chromate, sulfite, oxalate, calcium and strontium ions interfered with the determination of the analyte. The present method was applied to the determination of sulfate in tap water.
