电解液中硼酸含量的测定 应用资料

电解液中硼酸含量的测定 应用资料电解质溶液中的硼酸含量根据JIS K8863-2007硼酸(试剂)进行定量分析。向样品中加入甘露醇和纯水后，用0.1mol/L氢氧化钠滴定至终点。终点是滴定曲线上的最大拐点。硼酸的浓度是根据滴定体积计算得出的。KGMKYOTO ELECTRONICSMANUFACTURING CO.，LTD.TIO-94008enL Application Memo Boric Acid in Electrolyte 1.Overview Boric acid in the electrolyte solution i s quantified according to J IS K 8863-2007 Boric acid (Reagent). After mannitol and pure water are added to the sample， it is titrated with 0.1mol/L sodium hydroxide up to the endpoint. The endpoint is the maximum i nflexion point on the titration curve. The concentration of boric acid is calculated from the titration volume. 2.
