摘　　要：通过二乙烯三胺改性麦秸秆(MWS),显著提高了其对阴离子染料亮绿(LG)的吸附能力。研究结果表明:酸性条件和升温有利于吸附,盐类存在不利于吸附,静电引力在吸附过程中起着主要的作用,在LG初始浓度为600mg/L,溶液pH=2,溶液温度30℃,吸附时间为350min条件下,MWS对LG的吸附量最高达到496mg/g。Wheat straw was modified by diethylenetriamine with epichlorohydrin and the adsorption quantity toward anionic dye light green was significantly enhanced.The results showed that it was favor of adsorption at pH=2 and coexisted common salts was opposite.The adsorption quantity was to 496 mg/g at the conditions of t=30℃,pH=2 and contact time=350 min.
