| 摘 要： | The adsorption properties of XSD-296 for Cr（Ⅵ） were studied by using chemical analysis and infrared spectrometry. Experimental results show that XSD-296 resin has a good adsorption ability for Cr（Ⅵ） at pH=2.6 in the HAc-NaAc medium. The statically saturated adsorption capacity is 235 mg/g resin. The apparent activation energy of adsorption reaction, Ea, is 16.73 kJ/mol, and the thermodynamic parameters are △H=11.62 kJ/mol, △G298 K=-4.13 kJ/mol. The adsorption behavior of resin for Cr（Ⅵ） is in accordance with Freundlich adsorption isotherm. Cr（Ⅵ ） adsorbed on resin can be eluted by 5%NaCl-5%NaOH or 5%NH4Cl-5%NH3-H2O quantitatively. Infrared spectra and adsorption mechanism show that the functional group of resin coordinates with Cr（Ⅵ） to form co-ordination compound. The coordination molar ratio of the functional group of resin to Cr（Ⅵ） is 1：1.

| Abstract: | The adsorption properties of XSD-296 for Cr(VI) were studied by using chemical analysis and infrared spectrometry. Experimental results show that XSD-296 resin has a good adsorption ability for Cr(VI) at pH=2.6 in the HAc-NaAc medium. The statically saturated adsorption capacity is 235 mg/g resin. The apparent activation energy of adsorption reaction. Ea, is 16.73 kJ/mol, and the thermodynamic parameters are ΔH=11.62 kJ/mol, ΔG298 K=-4.13 kJ/mol. The adsorption behavior of resin for Cr(VI) is in accordance with Freundlich adsorption isotherm. Cr(VI) adsorbed on resin can be eluted by 5%NaCl-5%NaOH or 5%NH4Cl-5%NH3 · H2O quantitatively. Infrared spectra and adsorption mechanism show that the functional group of resin coordinates with Cr(VI) to form co-ordination compound. The coordination molar ratio of the functional group of resin to Cr(VI) is 1:1. |
