薄膜清洗液中氢氧化钾含量的测定 应用资料样品加水后，用1mol/L盐酸滴定法测定薄膜清洗液中的氢氧化钾含量。终点是滴定曲线上的最大拐点。氢氧化钾的浓度是根据盐酸的滴定体积计算得出的。KGMKYOTO ELECTRONICSMANUFACTURING CO.，LTD.TII-93001enL Application Memo Potassium Hydroxide in Film Cleaning Liquid 1.Overview Potassium hydroxide i n the f ilm cleaning l iquid is measured by titration with 1mol/L hydrochloric acid after the sample i s added with water. The endpoint is the maximum inflexion on the titration curve. The concentration of Potassium hydroxide is calculated from the titration volume of hydrochloric acid. 2. Apparatus Main unit Automatic potentiometric t itrator (preamplifier STD) Electrode pH glass electrode Ceramic reference electrode Temperature compensation electrode 3. Reagents Titrant 1mo1/L hydrochloric acid Solvent Pure water 4. Example Please feel free to contact us for any further i nformation. Kyoto Electronics Manufacturing Co.， Ltd.
