中文摘要：

文章选用FeCl2与FeCl3浸渍颗粒活性炭制成复合材料（GAC-Fe（Ⅱ）、GAC-Fe（Ⅲ）），并用扫描电镜（SEM）对复合材料GAC-Fe（Ⅱ）、GAC-Fe（Ⅲ）进行表征．研究比较两种复合材料在不同初始浓度和不同DH条件下去除水中溴酸盐BrO3-的效果，使用吸附等温模型和吸附动力学模型对实验结果进行分析。并探讨其反应机理．结果表明，初始浓度16.7mg／LGAC-Fe（Ⅲ）效果优于GAC-Fe（Ⅱ），BrO3-去除率可达98％；去除率随pH值3-9的升高而下降；吸附等温实验表明．Langmuir吸附等温式能更好的描述材料对BrO3^-的吸附过程及材料的吸附效果；吸附动力学实验表明材料去除BrO3^-更符合准二级吸附动力学模型．

英文摘要：

Composite materials （GAC - Fe （Ⅱ）, GAC - Fe （Ⅲ）） are made from FeCl2 and FeCl3 impregnated granular activated carbon （GAC-Fe） in the experiment and are characterized by SEM. Two kinds of composite material removal bromate in different initial bromated concentration and pH conditions are compared; the study results are analyzed by adsorption isothermal model and the adsorption dynamics model, and its reaction mechanism is discussed. The results show that at initial bromate concentration 16.7 mg/L condition, the GAC- Fe（Ⅲ） is better than GAC-Fe（Ⅱ）, the removal rate is 98 %; GAC-Fe（Ⅱ）, GAC-Fe（Ⅲ） removal rate of BrO3- decreases along with the increase of pH 3-9. Adsorption isotherm experiments show that the Langmuir adsorption isotherm could fit the experimental data well; the adsorption kinetic studies show that the material removal of BrO3 could fit the second-order dynamic adsorption model.
