摘要
壳聚糖是一种用途广泛的天然高分子阳离子型吸附剂,具有吸附分离水溶液中酸性染料的能力。研究结果表明,壳聚糖对酸性染料的吸附能力受到吸附剂的脱乙酸化度、颗粒直径、吸附时间以及溶液中乙酸含量等因素的严重影响。在最佳吸附条件下,壳聚糖对酸性红A和酸性湖蓝V的吸附回收率可达95%以上。
Chitosan, a natural macromolecule, is widely used as a kind of cationic absorbent. It has a good absorbility for anionic dyes from polluted water. The experimental results show that the absorbility is significantly affected by many factors, including deacetylation degree, particle diameter, absorbing time and the concentration of acetic acid etc. Under the best experimental conditions, the value of recovery of Acid Red A and Acid Turquoise Blue V is higher than 95%.
