【摘要】 对12.0 mol/LNaOH浓液中FeO42-的分解过程动力学进行了研究,测定了不同分解反应温度下FeO42-分解浓度与反应时同的关系。实验结果表明,FeO42-的分解反应为一级反应,分解活化能为58.1 kJ·mol-1,分解反应的速率方程:γ=1.15×105·exp(-58.1/RT)·CFeO42-。当系统的分解温度为30℃、40℃、50℃下的半衰期分别为17.40h、8.46 h、4.17 h。更多还原

【Abstract】 The decomposition kinetics of Ferrate (Ⅳ) ion was studied in 12.0 mol/L NaOH solutions.The deckmposition rates were determined at different operlting temperatures.The experimental results showed that the decomposition was firstorder reaction,the reaction activity energy was 58.1 kJ·mol-1,and the decomposition reaction rate equation could be described as:γ=1.15×105·2exp( -58.1/ RT)·CFeO2-. The half - life t1/2 was 17.4 h,8.46 h and 4.17 h at 30℃,40℃,50℃ reaction temperature respectively.更多还原
