摘要
以淀粉(ST)为原料、通过600℃的温度处理成炭材料(CST),将对苯乙烯磺酸钠(PSSS)接枝到CST表面,成功制备出一种新型材料PSSS-gCST。并采用静态法研究了PSSS-g-CD301对Fe3+的吸附行为。结果表明,PSSS-g-CD301材料对Fe3+离子具有很强的吸附能力,最大吸附容量可分别达到I6.gm g-1。吸附速率快,,且吸附容量随温度升高而减小.随pH增大而增大。
The sodium styrene sulfonate(SSS) is grafted onto the surface of Starch which is carbonized at the heat of 600℃,obtaining the grafted material PSSS-g-CST.The adsorption behaviour of PSSS-g-CST for Fe3+ is investigated in this paper using static method.The results showed that the adsorption rate is very fast and the adsorption capacity increased with the increase of temperature and the value of pH.
