Dye Adsorbent Prepared by Crosslinking of Poly(γ-glutamic acid) and Gelatin

Abstract:

The present paper describes the preparation of novel biodegradable adsorbent based on cross-linking of poly (γ-glutamic acid) (γ-PGA) and gelatin and characterization of its Rhodamine B dye adsorption capability. Cross-linking effect was measured with the effect of adsorbent adsorbing ionic dyes Rhodamine B. In the experiment, the various factors which had influence on the adsorption effect, including preparationtemperature, preparation pH value, concentrations of cross-linking agent, cross-linking time were analyzed. The results showed that the adsorbent had good adsorption performance after cross-linking. The adsorbent was characterized by fourier transform infrared spectrum (FTIR), revealing that there were amide bonds between gelatin and poly (γ-glutamic acid) by cross-linking reaction.
