摘要
采用壳聚糖对酸性蓝黑B模拟废水进行处理,研究了溶液的酸度、吸附时间、溶液的初始浓度和溶液温度等对吸附效率的影响.结果表明,壳聚糖对酸性蓝黑B具有优良的吸附效果,在溶液初始浓度小于400 mg/L,pH=3.5～6,温度约为30～40 ℃,吸附处理30～40 min, COD去除率可达90%以上.
In this article the adsorption of chitosan for acid black blue-B dye wastewater is investigated. The effect of several factors, such as the dye concentration, pH value, settling time, and temperature on COD removed is studied. The result shows that chitosan has a good adsorption on acid black blue B, with a rate of COD removed up to 90% after being treated in pH = 3.5 - 6, 30- 40 ℃ ,the concentration of less 400 mg/L, for 30 - 40 min.
