金属有机骨架材料的制备及其对绝缘油中氨基比林的吸附研究

Study on Preparation of MOFs and Their Adsorption of Aminophenazone in Transformer Oil

本文采用溶剂热法制备了3种金属有机骨架材料MOF-505、Cu-BTC、MIL-100(Fe),优选了具有最高吸附量的吸附剂Cu-BTC。接着系统研究了Cu-BTC与活性炭、13X分子筛和活性白土在不同初始浓度和吸附温度下对氨基比林的平衡吸附量。利用分子模拟软件进行模拟计算并解释3种MOF材料对氨基比林的吸附特性差异。结果表明:Cu-BTC对氨基比林的吸附量远高于其他3种吸附剂;不同温度下Cu-BTC对不同初始浓度氨基比林的平衡吸附量有较大差异,应采用合适的吸附温度,达到最优的吸附容量。

In this paper,three metal-organic framework(MOF)materials MOF-505,Cu-BTC,and MIL-100(Fe)were prepared by solvothermal method,and Cu-BTC with the highest adsorption capacity was selected.The equilibrium adsorption capacity of Cu-BTC,activated carbon,13X molecular sieve,and activated clay at different initial concentrations and adsorption temperatures was systematically studied.The difference among the adsorption characteristics for aminophenazone of the MOFs was explained by simulation calculations using simulation software.The results show that the adsorption capacity for aminophenazone of Cu-BTC is much higher than that of the other three adsorbents.Under different temperature,the equilibrium adsorption capacity of BTC for aminophenazone at different initial concentrations has much difference,thus the appropriate adsorption temperature should be selected to achieve the optimal adsorption capacity.
