次氯酸钠溶液中有效氯含量的测定 应用资料在样品溶液中加入碘化钾和1mol/L硫酸后,用0.1mol/L硫代硫酸钠溶液滴定,测定次氯酸钠的浓度。终点是滴定曲线上的最大拐点。次氯酸钠浓度由硫代硫酸钠的滴定体积计算得出。KGM KYOTO ELECTRONICSMANUFACTURING CO.,LTD.TIQ-97001enL Application Memo Sodium Hypochlorite Concentration Industry Inorganic chemical i ndustry Instrument Automatic potentiomet r ic t itrator Measurement method Redox titration, GB 19106 1.Overview After adding potassium iodide and 1mol/L sulfuric acid t o the sample solution, sodium hypochlorite concentration is measured by titration with the 0.1mol/L sodium thiosulfate solution. The endpoint is the maximum inflexion on the titration curve. The sodium hypochlorite concentration is calculated from the titration volume of sodium thiosul f ate. 2.Apparatus Main unit Automatic potentiomet r ic t itrator (preamplif i er STD) Electrode Platinum electrode Ceramic reference electrode 3.Reagents Titrant 0.1 mol/L sodium thiosulfate solution Additive Potassium iodide, 1mol/L sulfuric acid 4.Example -Measurement results- Average (%) 1.0113 SD(%) 0.0146 RSD(%) 1.44 -Titration curve- Please feel free to contact us for any f urther i nformation.
