微晶纤维素对苯酚吸附行为的探究

Study on the Adsorption Behavior of Phenol on Microcrystalline Cellulose

采用水浴振荡法研究微晶纤维素对苯酚的吸附行为,分别考察了pH值,时间,温度和微晶纤维素溶胀处理前后对吸附过程的影响。结果表明,pH=7时,吸附率最大为42%;吸附时间为4h,吸附达到平衡。微晶纤维素对苯酚的吸附,受温度影响较小。溶胀后的微晶纤维素对苯酚吸附效果明显好于未溶胀的微晶纤维素。

The adsorption of phenol by microcrystalline cellulose was studied with the water bath suceussion method. The effects of pH value, time, temperature and swelling treatment for microcrystalline cellulose on the adsorption progress were investigated. The experimental results showed that the adsorption rate reached the maximum （42%） when pH=7; the adsorption would achieve balance when the adsorption time is 4 hours; the tem- perature has slight effect on the adsorption of phenol by microcrystalline cellulose; and the microcrystalline cellulose after swelling treatment would have an obviously better adsorption effect than the untreated one.
