Study on the Catalytic Action of FeⅡon the Formation Reaction of Zinc Ferrite
摘要/Abstract
摘要：
研究了微量FeⅡ对铁酸锌生成反应的催化作用,测定了反应的活化能,探讨了催化剂种类、用量及反应物浓度对相转化过程的影响.结果表明,该反应的活化能为48.31kJ/mol,催化剂的用量对相转化速率影响较大,当n(FeⅡn(FeⅢ)一定时,相转化速率与反应体系的初始浓度无关.
Abstract：
The formation reaction of ZnFe2O4in the presence of trace amount of FeⅡwas studied. Some kinetic parameters such as the reaction rate constantsat different initial concentrations and the activity energy of the reaction were determined. The effect of the variety of catalystsand the amount of FeⅡ used as catalyst on the reaction was investigated respectively . The results reveal that the activity energy of the formation reaction of ZnFe2O4 is 48. 31 kJ/mol.
