【摘要】 本文发现在硫酸介质中,钛（Ⅳ）催化高碘酸钾氧化中性红褪色的新指示反应,研究了反应的动力学条件,建立了催化褪色光度法测定痕量钛（Ⅳ）的新方法,灵敏度为2.8×10^-11Ti⁴⁺/ml。更多还原

【Abstract】 Ti（IV）can catalyze the decolourizing reaction formed by the oxidation cf neutral red with KIO₄ in a H₂SO₄ solution. The cptimum conditions influencing the rate of catalytic decolourizing reaction and a new high selectivity method for determining trace Ti（Ⅳ）were established. The sensitivity of the method is 2. 8×10^-11gTi（Ⅳ）/ml.更多还原
