摘要
研究了痕量锗(Ⅳ)在稀硫酸介质中催化加速碘酸钾、过氧化氢与中性红之间的反应及其动力学条件。该反应为一级反应,表观速率常数为1.69×10^(-3)/s;半衰期T_(1/2)为6.82min。建立了催化光度法测定痕量锗(Ⅳ)的新方法。
It was found that tract germanium ( Ⅳ ) in sulfuric acid medium could catalyze the decoloring reaction among potassium iodate, hydrogen peroxide and neutral Red. The kinetic conditions of the reaction were studied. This reaction belonged to first order reaction. The apparent ratio constant of this reaction was 1.69×10-3/s. The period of half change of this reaction was 6.82 minutes. The new method to determine trace Ge (Ⅳ ) by kinetics spectrometer was described.
