摘要
初步探讨了金属-有机骨架材料MOF-199对甲醛气体的吸附性能。采用分光光度法测定MOF-199对甲醛气体的吸附量,研究了吸附量与吸附温度及吸附时间的关系,并探讨了MOF-199对甲醛的吸附机理,提出了一种测定MOF-199对甲醛吸附量的方法。结果表明,在50℃、6h的吸附条件下,MOF-199对甲醛气体的吸附量最大,达到83.84mg/g;MOF-199对甲醛气体具有较好的吸附效果。
The adsorption performance to formaldehyde vapor of metal-organic frameworks MOF-199 is studied. Amount of formaldehyde vapor adsorbed by MOF-199 is determined by spectrophotometry and the relation among adsorption amount, time and temperature is studied. Furthermore, the adsorption mechanism to formaldehyde vapor of MOF-199 is discussed and the measuring method of adsorption is established. The results show that under these condi- tions （〈50℃ and 6h）, the amount of formaldehyde vapor adsorbed by MOF-199 reaches maximum（83. 84mg/g）. MOF-199 has good adsorptive effect to formaldehyde vapor.
