摘　　要：以研究壳聚糖微球对Ag+的吸附性能为目的,采用原子吸收的方法考察不同条件下壳聚糖微球对Ag+的吸附关系。结果发现,pH=7,T=30℃,AgNO3的初始浓度为40mg/L,壳聚糖微球质量为0.04g时,60min的吸附,其吸附率可以达到97.705%,80mg/L的Ni2+,Cu2+,Pb2+,Zn2+,Cr3+,Al3+虽然可被壳聚糖微球吸附,但不干扰测定。Studied the adsorption properties of hollow chitosan microsphere for Ag^＋ , and the relationship between chitosan and Ag^＋ in different conditions. The results showed that maximum removing rate of Ag^＋ reaches 97.7%, in effective treatment conditions, contacting time 60 min , T = 30 ℃, pH = 7.0 and the initial concentra tion of Ag^＋ is 80 mg/L.
