摘要

研究了硝酸银(AgNO3)和硫酸银(Ag2SO4)对银(I)的吸附作用。我们比较了壳聚糖水凝胶珠和壳聚糖醋酸酯的吸附能力，壳聚糖醋酸酯是制备壳聚糖水凝胶珠的初始溶液。我们建立了一个吸附动力学模型，假设扩散过程和化学反应同时发生。利用红外光谱和x射线光电子能谱证实并描述了吸附的化学性质。

ADSORPTION OF SILVER IONS ON CHITOSAN HYDROGEL BEADS

We investigated the adsorption of silver(I) from silver nitrate (AgNO3) and silver sulphate (Ag2SO4). We compared the adsorption ability of chitosan in the form of hydrogel beads with that of chitosan acetate – an initial solution from which the beads were derived. We developed a model of adsorption kinetics, assuming the simultaneous occurrence of the diffusion process and the chemical reaction. We confirmed and described the chemical nature of adsorption based on the Fourier-transform infrared and X-ray photoelectron spectra.
