摘要:
制备了壳聚糖/滑石粉复合物吸附剂,用于对水溶液中刚果红的吸附.考察了刚果红溶液的初始浓度、吸附剂用量、时间对吸附的影响.结果表明,初始浓度为100 mg/L,吸附剂用量为1.0 g/L时,吸附60 min达到平衡,刚果红的去除率为96%.壳聚糖/滑石粉复合物对刚果红的吸附过程符合Langmuir等温吸附模型,最大吸附量为253.8 mg/g.吸附动力学研究表明,吸附行为符合伪二阶动力学模型.
Abstract:
Chitosan / talcum composite was prepared and used as adsorbent for the adsorption of congo red in aqueoussolution. Effects of initial congo red concentration,adsorbent dosage and contact time on the adsorption of congored were investigated. It was found that after 60 minutes,the removal percent of congo red attained to 96% at initialcongo red concentration of 100 mg /L and adsorbent dosage of 1. 0 g /L. The equilibrium adsorption data fitted inwith the Langmuir model via linear regression analysis,and the maximum adsorption capacity for congo red was253. 8 mg /g. The kinetic investigation showed that the adsorption followed the pseudo-second order equation.
