明胶水凝胶对染料的吸附作用研究

Study on Adsorption of Dyes by Gelatin Hydrogel

本文通过明胶(Gelatin,GEL)配制形成的水溶液,制备了GEL水凝胶,测定了其对染料的吸附性能,以及明胶交联对阴离子染料的吸附性能,进而用紫外光谱表征了GEL水凝胶的吸附性能,结果表明,GEL水凝胶对两性染料具有良好的吸附效果且交联过后的明胶吸附性能显著提高。

GEL hydrogels were prepared by gelatin(GEL) configuration of aqueous solution. The adsorption properties of dyes and the adsorption properties of gelatin crosslinks on anionic dyes were determined. The UV spectra were used to characterize the adsorption performance ofGEL hydrogels.The results show that GEL hydrogel has a good adsorption effect on amphoteric dyes and the gelatin adsorption performance after cross-linking is significantly improved.
