摘要： 脱乙酰壳多糖高分子链中含有大量的游离氨基, 表现出良好的螯合和吸附性质, 它对重金属离子的螯合作用已有许多报道, 但对非金属物质的吸附研究相对较少[1]. 本文报道了脱乙酰壳多糖膜在不同条件下对卤素碘的吸附作用。

关键词: 脱乙酰壳多糖, 膜, 碘, 吸附

Abstract: Chitosan film exhibited a high ability of absorbing iodine in aqueous solution and the ability was increased with increase of the deacetylation degree of chitin. The iodine adsorption ability of chitosan film was independent of the thickness of the film. In organic solvents the absorbition ability was larger in polar solvents than in nonpolar solvents.

Key words: chitosan, film, iodine, adsorption
