利用水热法合成铁掺杂介孔氧化硅?石墨化炭复合物（ FeMS），并对其进行结构表征，发现其具有介孔结构，且高铁含量的FeMS含有明显的石墨化炭物种。比较了传统吸附剂活性炭、SBA?15及FeMS分别对橙黄Ⅱ的吸附性能，考察了初始pH、投加量、初始浓度、吸附时间对吸附的影响，并对吸附过程进行了动力学研究和吸附等温模型的模拟。结果表明：FeMS对橙黄Ⅱ有很好的吸附性能，且高铁含量的FeMS吸附量优于低铁含量；FeMS吸附橙黄Ⅱ的最佳pH值为7，最高吸附量能达到1108 mg·g－1；初始浓度对橙黄Ⅱ吸附效率有明显的影响；对低浓度的橙黄Ⅱ，可在120 min内达到吸附平衡；FeMS对橙黄Ⅱ的吸附动力学数据符合准二级动力学模型；FeMS对低浓度橙黄Ⅱ的吸附符合Henry等温模型，饱和吸附量与橙黄Ⅱ的浓度有关。

Iron doped mesoporous silica?graphitized carbon compound ( FeMS ) was synthesized by hydrothermal method. Characterization was carried out, which indicated that FeMS has a mesoporous structure and the one with high iron content has obvious graphitized carbon species. Comparison of adsorption performance with traditional adsorbent activated carbon and SBA?15 was performed. And the influences of initial pH, dosage of adsorbent, initial concentration and adsorption time on adsorption were studied. In addition, adsorption kinetics process and adsorption isothermal model were analyzed. The results were as follows: FeMS showed quite good adsorption performance than other adsorbents, while one with high iron content has better adsorption ability than those with low iron content. The optimal pH value for adsorption was 7 and the adsorption capacity reached 1108 mg·g-1 . Initial concentration of OrangeⅡhad distinct effects on the adsorption efficiency. For low concentration solutions of Orange Ⅱ, the adsorption equilibrium was reached within 120 minutes. The adsorption kinetics of Orange Ⅱ onto FeMS conformed to the pseudo?second?order kinetic model. The adsorption of low?concentration OrangeⅡonto FeMS fitted the Henry isothermal model, suggesting that the adsorption capacity has correlation with the concentration of Orange Ⅱ.
