薇甘菊吸附亚甲基蓝的研究

Study on Absorption of Methylene Blue by Mikania micrantha

研究薇甘菊活体在不同pH值、初始浓度、吸附时间条件下对水体中亚甲基蓝的吸附能力,并对薇甘菊的再生及重复吸附能力进行测试。结果表明：常温下,在亚甲基蓝溶液浓度为5-20 mg/L、pH值为8的亚甲基蓝溶液中,薇甘菊活体培养3 d后对亚甲基蓝的去除率可达99%。同一株薇甘菊可以在浓度为10 mg/L、pH值为8的亚甲基蓝溶液中循环培养4次吸附效果最佳,去除率均可达到90%以上,吸附效果良好。

The absorption capacity of Mikania micrantha on methylene blue in water was studied in different pH,initial concentration and absorption time,and its regeneration and repeated absorption capacity were also tested. The removal efficiency of M. micrantha on methylene blue was 99% at methylene blue concentrations of 5 ~ 20 mg/L,methylene blue at pH 8,and M. micrantha in vivo after 3 d. The same strain of M. micrantha could be cultured for 4 times in methylene blue solution with concentration of 10 mg/L and pH 8 at this time absorption capacity was best,and the removal rate could reach more than 90%.
