摘要
硅藻土因良好的理化特性和低廉的价格而备受科研人员的关注。文章用硅藻土负载壳聚糖对甲基橙染料进行吸附研究,讨论了染料吸附的影响因素。结果表明:吸附时间为20 min、壳聚糖负载量为0.1 g·g-1、染料初始浓度为10 mg·L-1、染料pH为4、温度为30℃时,复合材料对甲基橙染料的吸附效果最好,对甲基橙的脱色率可达93.17%。
Diatomite has attracted considerable attention due to their enhanced physical and chemical behavior and its low cost. The diatomite is used for absorbent, and methyl orange dye is used for absorbate in this thesis. The influence factors of dye adsorption were discussed. The results revealed that when the adsorption time is 20 min, chitosan＇s dosage is 0.1 g·ga, initial concentration of dye is 10 mg·L-1, pH is 4, temperature is 30 ℃, the adsorption of methyl orange dye get the optimum condition and removal rate of it is 93.17 %.
