摘要
采用静态固相吸附法研究了不同性质的氧化铝吸附甲醛的动力学,并与真空条件下的氧化铝对甲醛气体的吸附量进行了比较,结果发现真空条件下的氧化铝(分析纯)对甲醛气体的吸附量近乎是常温常压条件下的氧化铝(分析纯)对甲醛气体吸附量的2倍,其他性质的氧化铝在常温常压条件下对甲醛气体的吸附量也很大,但是不同粒度的活性炭吸附甲醛气体的吸附量略大于氧化铝.
In this study, the adsorption capacity of different properties of alumina to formaldehyde gas was researched by static adsorption. Compared to pressure conditions, the adsorption capacity was two times in vacuum conditions. At the same conditions, compared to the activated carbon, the adsorption capacity of alumina to formaldehyde gas was poorer. The results showed that alumina and activated carbon can be used as a better adsorbent to remove indoor formaldehyde gas, and the adsorption effect of aluminum hydroxide to formaldehyde gas was poorer.
