摘　　要：研究了以ZIF-8为载体,FeSO_(4)·7H_(2)O为铁源制备的铁掺杂沸石咪唑酯基金属有机框架材料(Fe-ZIF-8)对染料废水中甲基橙的吸附;考察了Fe-ZIF-8吸附剂加入量、体系pH值、体系温度以及吸附时间对吸附效果的影响。实验结果表明:Fe-ZIF-8吸附剂适于常温状态下使用,可有效降低处理过程中的能耗。该体系对50 mL质量浓度为20 mg/L的甲基橙溶液的最佳吸附条件为:吸附剂加入量为0.06 g,pH值为7,体系温度为25℃,吸附时间为60 min。在此条件下,甲基橙的吸附率可达92.8%。Fe-ZIF-8,a kind of zeolitic imidazolate metal-organic frameworks,was prepared with ZIF-8 precursors and FeSO_(4)·7H_(2)O as iron source.This work studied on methyl orange waste water treatment through Fe-ZIF-8.The effects of Fe-ZIF-8 dosage,pH value,reaction temperature and time on the adsorption of methyl orange were studied.The results showed that Fe-ZIF-8 is suitable for use at room temperature,which can effectively reduce the energy consumption in the treatment process.The adsorption rate for 50 mL 20 mg/L(mass concentration)methyl orangesolution could reach 92.8%under the optimal conditions of 0.06 g Fe-ZIF-8,pH 7,25℃and 60 min.
