摘要
采用水热合成法,在金属有机骨架制备过程中加入活性组分H_6P_2W_(18)O_(62)制备吸附剂[Co(2,2'-bipy)_3]_3(P_2W_(18)O_(62));并采用IR等测试手段对其进行表征.用紫外分光光度法研究了合成的吸附剂对亚甲基蓝溶液的吸附性能,探讨了不同因素如pH、初始质量浓度及温度等对吸附容量的影响.结果表明溶液的pH值为10且高温有利于该吸附.动力学符合拟二级动力学,等温吸附符合Langmuir等温模型,并有利于吸附阳离子型染料.
The novel[Co（2,2＇-bipy）3]3（P2W18O62）adsorbent was prepared by hydrothermal synthetic method with H6P2W18O62 and Metal-organic frameworks as active species and supports,respectively.[Co（2,2＇-bipy）3]3（P2W18O62）was characterized its composition and structure by IR.Uv-vis spectrophotometry was used to study the adsorption of methylene blue on[Co（2,2＇-bipy）3]3（P2W18O62）in aqueous solution.The effects of the experimental parameters,including pH,initial concentration,and temperatures etc.were investigated.The results showed that pH of 10 and high temperature were beneficial to the dye adsorption.The experiment data could be well described by pseudo-sencond-order kinetic model and Langmuir isotherm model,and showed well adsorption properties to cationic dyes.
