摘　　要：采用氯化锆与2,2'-联喹啉-4.4'-二甲酸在溶剂热反应条件下,合成了多孔的Zr-有机骨架(Zr-MOF)材料,并用其对阳离子翠蓝X-GB和活性黄棕K-GR分别进行物理吸附和光催化降解.结果表明,Zr-MOF在500 min内对单一染料溶液中阳离子翠蓝X-GB的吸附效率高达99.76%,在与活性黄棕K-GR的混合染料溶液中对阳离子翠蓝X-GB的选择性吸附达到了98.62%。在紫外光照射下,Zr-MOF在120 min内几乎可将阳离子翠蓝X-GB完全催化降解,110 min后对活性黄棕K-GR的光催化降解效率为75.25%。经过4次循环后,Zr-MOF对阳离子翠蓝X-GB的吸附效率仍可达97.13%;对阳离子翠蓝X-GB和活性黄棕K-GR的光催化降解效率分别为96.59%和71.28%。A porous Zr-organic framework(Zr-MOF)material is synthesized by the solvothermal reaction of zirconium chloride with 2,2,-biquinoline-4,4'-dicarboxylic acid.It is used for physical adsorption and photocatalytic degradation of Cationic Turquoise Blue X-GB and Reactive Yellow Brown K-GR dye,respectively.The results show that the adsorption efficiency of Cationic Turquoise Blue X-GB in single dye solution is 99.76%in 500 min,and 98.62%in mixed dye solution with Reactive Yellow Brown K-GR.Under UV irradiation,Zr-MOF can almost completely degrade Cationic Turquoise Blue X-GB within 120 min,and the photocatalytic degradation efficiency of Reactive Yellow Brown K-GR is 75.25%after 110 min.After four recycles,the adsorption efficiency of Zr-MOF on Cationic Turquoise Blue X-GB is still 97.13%,and the photocatalytic degradation efficiency of Cationic Turquoise Blue X-GB and Reactive Yellow Brown K-GR are 96.59%and 71.28%,respectively.
