摘要
0Cr18Ni9、1Cr13不锈钢是餐具常用的材料,通过试验建立了反应机理的反应体系,测定了在不同温度、酸度和盐浓度的溶液中铬的迁移量,应用化学动力学的理论,推导了反应机理,计算了反应速率常数。
0Cr18Ni9 and 1Cr13 stainless steels are typical materials for cutlery.A reaction system for studying the reaction mechanism was built.Cr concentration was determined at different temperatures,different acidity and different Na Cl concentrations.Using the theory of chemical kinetics,the reaction mechanism was derived,the reaction rate constants were calculated.
