Abstract
[Objective] To establish a simple method for detecting Hydroxy-benzenesulfonic acid monosodium salt sodium phenolsulfonate content.[Methods] Bromimetry was applied for measuring the sample concentration and starch indicator was used to determine the end point.[Results] The experiment showed that the standard deviation of Hydroxy-benzenesulfonic acid monosodium salt sodium phenolsulfonate content is 0.004 688,accuracy is 3.57%.[Conclusion] Determination of Hydroxy-benzenesulfonic acid monosodium salt sodium phenolsulfonate with bromimetry has high precision and accuracy.The method is simple and rapid,it can be used for the determination of Hydroxy-benzenesulfonic acid monosodium salt sodium phenolsulfonate.
