Abstract

Abstract: The zircon cross linked with carboxyl methyl konjac glucomannan gel microspheres (CMKGM-Zr) were prepared by crosslinking oxygen zirconium ion (ZrO²⁺) and carboxyl methyl konjac glucomannan (CMKGM) which was obtained through rectifying konjac glucomannan(KGM) with carboxyl-methyl. Structure of the CMKGM-Zr was characterized by scanning electron microscopy and the change between pre- and post-adsorption reaction was analyzed by infrared spectroscopy. On this basis, the adsorption capacity of CMKGM-Zr for benzoic acid was studied. And the parameters, including the adsorption time and pH were investigated. Further, according to adsorption isotherms of CMKGM-Zr for benzoic acid, thermodynamic parameters of the adsorption process were calculated and the experimental data were fitted. The results showed that the gel microspheres prepared with 2.0 % CMKGM and ZrO²⁺ were white irregular geometry of hollow spheres and the mechanical strength was 15.3 g. The reaction between ZrO²⁺ and —COO^- occurred after adsorption of benzoic acid. When the temperature 298 K, pH 4.5, and the concentration of benzoic acid 200 mg/L were used, the adsorption equilibrium was established about 4 hours. And the dsorption capacity of CMKGM-Zr for benzoic acid reached the maximum of 79.964 2 mg/g. Freundlich equation was suitable for the adsorption of the studied system. Adsorption driving forces were the enthalpy change and entropy change.

Key words: konjac glucomannan (KGM), carboxyl methyl, benzoic acid, zircon gel microphere, adsorption
