Abstract

Abstract: In order to investigate the adsorption ability of regenerated cellulose aerogel to iodine vapor, regenerated cellulose spherical aerogels(RCSA) were prepared from natural bamboo fibers and then Ag₂O/RCSA were fabricated by adsorption and reaction of ammine silver complex ion on the surface of cellulose. In addition, the adsorption ability to iodine was studied by taking ¹²⁷I as the radioisotope of ¹³¹I. The morphology, crystal form and pore structure of Ag₂O/RCSA were characterized and analyzed by scanning electron microscopy(SEM), transmission electron microscopy(TEM), X-ray diffraction(XRD) and BET specific surface area. The results showed that the color of RCSA turned from white to brown with the appending of Ag₂O nanoparticles, but the original three-dimensional network structure cellulose aerogels didn't change. Ag₂O nanoparticles uniformly distributed in the cellulose backbone and closely combined with cellulose. Both N₂ adsorption and desorption isotherms of RCSA and Ag₂O/RCSA exhibited the characteristics of type Ⅳ isotherms. The BET specific surface area and BJH pore volume of Ag₂O/RCSA decreased obviously compared with those of RCSA, and there was little change in the size of the average pore diameter. The adsorption of Ag₂O/RCSA to iodine vapor was physical adsorption by porous aerogel and chemical adsorption by turning Ag₂O into AgI, and the total iodine vapor adsorption capacity of Ag₂O/RCSA was 87.8 mg/g.

Key words: cellulose, aerogel, Ag₂O, iodine adsorption properties
