Study on Preparation and Adsorption Performance of Gelatin Microspheres for Cr(VI)

Abstract:

A novel microspheres adsorbent was prepared by the emulsion-congealed crosslinking method. The gelatin was as raw material and glutaraldehyde was as the crosslinking agent. The SEM images showed that the product was spherical, the distribution was uniform and not sticky. The TG result showed that the thermal decomposition form of gelatin microspheres was single and the thermostability was good. The XRD results indicated that the crystalline state of gelatin had not been affected by crosslinking of glutaraldehyde. The adsorption performance of gelatin microspheres to Cr(Ⅵ) was studied by the static adsorption experiments. The application conditions were optimized by single-factor experiment. The results showed that the optimum conditions were that pH was 3.0, temperature was 35°C and time was 1.5h.
