膨润土-壳聚糖复合材料对罗丹明吸附行为的研究
Behavioral Study of Adsorption of Rhodamine by Bentonite-chitosan Composites
摘要
Abstract
In this paper, bentonite-chitosan composites were adopted as adsorbent to study the adsorption of RhB from the simulated RhB-contained solutions. The effects of chitosan loading amount, pH, adsorption time, and initial concentration of RhB solution on the adsorption were studied in details and the adsorption isotherm and adsorption mechanism were analyzed as well. The results showed that the optimal chitosan loading amount was 0.005 g/g and the optimal pH was 6. The adsorption amount increased with the increase of adsorption temperature. During the adsorption process, chemical adsorption occupied the dominant position. The experimental data indicated that Langmuir model could describe the process properly.关键词
