摘　　要：以金属有机骨架化合物MOF-199为基础材料,分别添加氧化石墨烯(GO)和掺杂金属Zn,制备GO@MOF-199和Zn@MOF-199复合材料,以解决MOF-199在含酚废水处理中低吸附量的问题。通过X射线衍射(XRD)、扫描电镜(SEM)+能谱仪(EDS)、红外光谱(FTIR)和比表面积检测(BET)对制备的吸附材料进行物性、表面形态、元素构成和比表面积的表征分析。结果表明,改性后的复合材料对酚类物质的吸附率远高于基础材料MOF-199,其中GO@MOF-199的吸附量最高,在吸附时间60 min,吸附温度30℃、w(吸附剂)=1%的最佳条件下,吸附量为72.33 mg/g。GO@MOF-199 and Zn@MOF-199 were prepared by adding graphene oxide(GO)and doped metal Zn,respectively,using MOF-199 as the base material,in order to address the low adsorption capacity of MOF-199 in phenol-containing wastewater treatment.The prepared adsorption materials were characterized and analyzed for their physical properties,surface morphology,elemental composition,and specific surface area using XRD,EDS-SEM,FTIR,and BET techn iques.Experimental results show that the adsorption rate of phenolic substances by the modified composite materials is much higher than that of the base material MOF-199.Among them,GO@MOF-199 exhibits the highest adsorption effect.Under the optimal conditions of 60 minutes of adsorption time,30℃adsorption temperature,and 1%adsorbent dosage,the maximum adsorption capacity can reach 72.33 mg/g.
