中文摘要：
微波辐射下,以壳聚糖为原料,甲醛为预交联剂,环氧氯丙烷为交联剂,制得甲醛环氧氯丙烷交联壳聚糖微球树脂,研究了合成条件对微球吸附性能的影响,并采用傅里叶红外光谱仪和电子扫描电镜对树脂的微观结构和形貌进行表征。结果表明,树脂具有很好的球形;Shiff碱反应能够很好地保护壳聚糖上的氨基;交联剂用量、搅拌速率和酸处理条件对树脂的吸附性能的影响较大。当合成条件为搅拌速率600r/min、甲醛1.5mL、环氧氯丙烷3mL、酸化时间8min、盐酸用量30mL,所得交联壳聚糖微球对Cu（Ⅱ）的吸附容量可达到269.83mg/g。
英文摘要：
With chitosan as the raw material, chitosan microspheres were prepared through crosslinked by form-aldehyde and epichlorohydrin under microwave irradiation. The influence of synthesis conditions on adsorption capacity of chitosan microspheres was investigated. The microstructure and morphology of crosslinked chitosan microspheres was characterized with FT-IR and SEM. The results show that dosage of crosslinking agent, stir- ring rate and treatment conditions with acid affect the properties of the resin largely. The resin has very good sphericity and the amino of chitosan could be protected by Schiff base. ＇When synthesis conditions are as fol- lows：stirring rate of 600r/min,dosage of formaldehyde 1.5mL, dosage of epichlorohydrin 3mL, time treatment with acid 8min, dosage of hydrochloric acid 30mL, the adsorption capacity of chitosan microspheres on Cu（ Ⅱ） could reach 269.83mg/g.
