摘要： 分别以环硫氯丙烷和环氧氯丙烷作为交联剂,合成交联壳聚糖树脂,测定其对Au(Ⅲ)的静态吸附性能.采用正交试验法全面考察了环硫氯丙烷交联壳聚糖(CCCS)树脂和环氧氯丙烷交联壳聚糖(ECCS)树脂吸附Au(Ⅲ)过程中,各主要因素对吸附性能的影响.结果表明,环硫氯丙烷交联壳聚糖树脂比环氧氯丙烷交联壳聚糖树脂所能适应的pH值、温度、初始离子浓度等条件范围更广,且在同样吸附条件下,环硫氯丙烷交联壳聚糖树脂比环氧氯丙烷交联壳聚糖树脂有更优良的吸附性能.环硫氯丙烷交联壳聚糖树脂对Au(Ⅲ)的吸附量可达296.67μg/mg,吸附率可达98.1%.

Abstract: Chloromethylthiirane and epichlorohydrin were used separately as crosslinking agents to crosslink with chitosan so as to synthesize them into two different resins of which the static adsorbilities to Au(III) were determined. The effects of each and main influencing factor of chloromethylthiirane crosslinked chitosan (CCCS) resin and epichlorohydrin crosslinked chitosan (ECCS) resin on their adsorbilities to Au(III) were also investigated by orthogonal tests. The results indicated that CCCS can be used wider in respect to its temperature, pH value and initial Au(III) concentrations especially its adsorbilities than ECCS under the same conditions. The adsorbility capacities of CCCS is up to 296.67 μg/mg with an adsorption rate 98.1%.
