  • 摘要: 实验初步研究了类芬顿试剂为吸收剂对气态元素汞的脱除性能,考察了铁盐种类、pH、初始汞浓度、反应温度、卤素离子、甲酸添加量等因素对类芬顿试剂脱除气态元素汞性能的影响.结果表明,在pH 3.5条件下,以氯化铁为催化剂时,气态元素汞的脱除效率为76.4%;添加250 μg·mL-1 Cl-、150 μg·mL-1 Br- 或5.0 μg·mL-1甲酸均可以显著提高类芬顿反应体系对气态元素汞的脱除效果,最高脱除效率可达95%以上.
    Abstract: Fenton-like reaction system was used to removal elemental mercury (Hg0) in this study. The effects of the experimental parameters on mercury removal were investigated. The parameters included iron salts, pH, mercury initial concentrations, temperature, the concentrations of halogen ions and formic acid. The result showed that the removal efficiency reached 76.4% at pH=3.5 using ferric chloride (FeCl3) as catalyst. The addition of Cl- (250 μg·mL-1), Br- (150 μg·mL-1) or formic acid (5 μg·mL-1) highly enhanced the removal efficiency. The maximum removal efficiency was over 95%.
