改性玉米秸杆纤维的制备及其吸附性能表征

The Preparation and the Characteristic of Adsorption Properties for Modified Cellulose of Core Straw

利用农副产品废弃物玉米秸杆中的纤维素与3-氯-2-羟基丙磺酸钠反应制备了改性玉米秸杆纤维,并根据对阳离子翠兰染料、Pb2+、Cu2的吸附量表征了其吸附能力。结果表明:改性玉米秸杆纤维对阳离子有强烈的吸附能力,且易于再生。

Strong cation exchanger 2-hydroxy-3-sulfpropyl-cellulose Na salt is prepared by modified cellulose of corn straw with ClCH_2CH(OH)CH_2SO_3Na . Further,its adsorption properties has been studied for cationic turquoise, Pb^(2+), Cu^(2+). The result shows that the modified cellulose of corn straw has stronger adsorption ability to cation and its regeneration is easy.
