锌-金属有机骨架材料对染料吸附性能的研究

Study on the adsorption performance of dyes by zinc metal organic framework materials

合成了锌金属有机骨架材料(Zn-Scb-MOF),测定了该金属有机骨架材料对有机染料亚甲基蓝、罗丹明B和甲基橙的吸附性能,考察了不同温度和初始质量浓度对该金属有机骨架吸附亚甲基蓝性能的影响.结果表明,该金属有机骨架吸附剂对亚甲基蓝、罗丹明B有较好的吸附能力,而对甲基橙的吸附能力较弱.该吸附剂对亚甲基蓝的吸附量随质量浓度增高而增长,25℃为该吸附剂的较佳吸附温度.

Zinc metal organic framework(Zn-Scb-MOF)was synthesized.The adsorption performance of methylene blue,Rhodamine B and methyl orange by the metal organic framework were determined.The effect of temperature and initial concentration on the adsorption of methylene blue was investigated.The results show that the metal organic framework adsorbent has good adsorption capacity for methylene blue and Rhodamine B,but weak adsorption capacity for methyl orange.The adsorption capacity of the adsorbent for methylene blue increases with the increase of the concentration,and 25℃is the better adsorption temperature of the adsorbent.
