摘要
在不同的壳聚糖浓度、pH和温度条件下,采用分光光度法测得吸附后的染料浓度,得到了壳聚糖对酸性染料的最佳吸附条件,即在固定染料浓度和体积的情况下,壳聚糖的投入量在500mg、pH值为6、温度为室温、吸附时间为2h左右条件下吸附最佳, 其结果将为利用壳聚糖处理印染废水提供一定的理论根据。
Under the condition of different chitosan concentration, pH and temperatures, adopting the spectrophotography to measure adsorb after the concentration of the dye, the authors got the best condition of adsorbing the chitosan for acid dye. Under the condition of fixedly the dye concentration and physical volume, the amount of devotion of the chitosan the adsorb was the best under the condition of 500 mg,pH was worth to 6, temperature for indoor temperature, time of adsorb 2. The results would be made use of the chitosan to treat the printing dye the waste water to provide the certain theories basis.
