摘要： 研究低浓度反应液状态下,以亚氯酸钠和盐酸为原料制备二氧化氯时,在不同温度和不同物料配比下亚氯酸钠转化率随时间的变化情况。并推断了低浓度状态下,亚氯酸钠和盐酸反应的动力学特征,获得宏观动力学方程。研究表明:低浓度反应液时以亚氯酸钠和盐酸为原料制备二氧化氯的反应,亚氯酸钠的表观反应级数为1,盐酸的表观反应级数为1.39。进一步求出反应的活化能和反应速率常数。本研究为二氧化氯发生器的研制提供了理论基础。

Abstract: The reaction rate of sodium chlorite was studied at various temperatures and molar concentrations of chlorite and hydrochloric acid at low concentrations. The reaction rate law was established, and macro kinetics formula was obtained. Reaction rates had been found as 1 and 1.39 apparent reaction order with respect to NaClO2 and hydrochloric acid respectively when the chloride dioxide was prepared at low concentrations of sodium chlorite and hydrochloric acid. The temperature dependence of the reaction was also investigated and pre-exponential Arrhenius parameter as well as activation energy were determined. The theoretical basis was laid for the reactor design and further development and application of the new technique. This study provides a theoretical basis for the design of chlorine dioxide generator.

Key words: low concentration, kinetics, apparent reaction order, sodium chlorite(NaClO2), chlorine dioxide(ClO2), activation energy
