The cellulose of luffa fibers was modified by NaIO 4to improve its adsorption capacity.After modification under the optimum conditions,the acridine yellow solution,methylene blue solution and their mixed solution were adsorbed with luffa fibers.The optimum treatment conditions of luffa fiber were studied from five aspects including dosage, temperature, mixing time, pH and concentration. The results showed that the optimal conditions are 30℃,pH=6.0,2.0 g/L dosage of luffa fiber and mixing time of 25 min.Under the optimum adsorption conditions,the adsorption rate of acridine yellow solution was 99.85%,and the methylene blue was 97.22%.In the mixed solution,the adsorption rate of acridine yellow was 98.61%,and the adsorption rate of methylene blue was 98.42%.%本文以丝瓜络中的纤维素为研究对象,通过氧化剂高碘酸钠改性改善其吸附能力.将丝瓜络在最佳条件下改性后,吸附吖啶黄溶液、亚甲基蓝溶液和它们的混合溶液,通过条件优化研究,确定了吸附温度30℃、pH值6、时间25min、吸附剂的投放量2.0g/L以及染料溶液的浓度2×10 -4mol/L.在最佳吸附条件下,吖啶黄溶液的最佳吸附率高达99.85%,亚甲基蓝的最佳吸附率达到了97.22%.混合溶液中吖啶黄的最佳吸附率为98.61%,亚甲基蓝的最佳吸附率为98.42%.
