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%.
