  • 摘要: 采用分光光度法和连续碘量法研究了二氧化氯(ClO2)氧化二价铁[JP2]离子的反应动力学。研究结果表明,该化学反应计量关系为:5Fe2＋+ ClO2 +4H+→5Fe3＋+Cl- +2H2O,建立了ClO2氧化二价铁离子的反应动力学方程为-rFe2＋≈1.6678×106EXP(-5179.7/T)[ClO2] [Fe2＋](pH=6.0);在pH=6.0和T=293 K的条件下,该反应对于ClO2和二价铁离子均为一级, 总反应级数为二级,二级反应速率常数k值为0.03556×103 L/(mol·s),该反应活化能Ea为43.1 kJ/mol;表明ClO2除铁的氧化反应在一般水处理条件下即能进行。
    Abstract: Kinetics of the reaction between iron(Ⅱ) and chlorine dioxide were studied by using continuous iodimetry and spectrophotometry. The results show that the stoichiometry is found to be 5Fe2＋+ ClO2 +4H+→5Fe3＋+Cl- +2H2O. The reaction kinetic equation is established as follows:-rFe2＋≈1.6678×106EXP(-5179.7/T)[ClO2][Fe2＋](pH=6.0). At pH=6.0 and water temperature of 293 K,the reaction of chlorine dioxide and iron(Ⅱ) is first order with respect to both chlorine dioxide and iron(Ⅱ),and the overall reaction is second order. The second order reaction rate constant k is 0.03556×103 L/(mol·s). The reaction activation energy found is 43.1 kJ/mol, which reveals that under usual water treatment conditions, using chlorine dioxide to remove iron(Ⅱ) in water is feasible.
