摘　　要：本文研究羧甲基壳聚糖对Fe2+的吸附性能,探讨了时间、PH值等对吸附性质的影响。PH=6时羧甲基壳聚糖对Fe2+最大吸附量为0.7mmol/g。并通过IR和UV光谱证实了羧甲基壳聚糖对Fe2+的络合作用。The characteristics about coordination of Fe^2 ＋ ions onto Carboxymethyl chitosan was investigated. The coordination conditions, such as tune and PHctc, were discussed. The uptake of Fc^2＋ at PH= 7 on carboxymcthyl chitosan was 0.7 mmol/g, IR and UV spectral results demonstrated the existence of complex compounds of Fe^2 ＋ with carboxymcthyl chitosan.
