【Abstract】 A rapid and accurate method for the determination of SO₄^2- in a cbromium bath plating with a silver electrode has been presented. The interfering substances in the bath are previously removed by means of column chromatograph in which Al₂O₃ is used to recover SO₄^2-. The best condition for the whole process have also been worked out.更多还原
