| 摘 要： | 采用壳聚糖小球吸附废水中的腐殖酸,探讨了反应时间、pH值、温度、壳聚糖小球用量、腐殖酸初始浓度等因素对壳聚糖小球吸附腐殖酸效果的影响,并测定了吸附等温线.结果表明：壳聚糖吸附腐殖酸的速率很快,50 min可达到吸附平衡;pH值和温度对吸附效果的影响不明显;壳聚糖小球用量对吸附效果的影响显著;在30℃下其吸附等温线符合Freundlich方程.

| Abstract: | Chitosan beads were used to adsorb humic acid from the waste water.The effects of the reaction time,pH values of solution,reaction temperature,dosage of chitosan beads and the different initiative solute concentration on the results of adsorption of humic acid by chitosan beads were studied.The results showed that the equilibrium of the adsorption could be obtained within 50 minutes,the effects of pH values and the temperature on the results of adsorption were not significant,while the effects of the dosage of chitosan beads on the results of adsorption were obvious,and that the adsorption isothermal curve accorded with the Freundlich Equation at 30℃. |
