Abstract

Abstract:

In order to reveal the adsorption properties of chitosan （CTS） and its derivative chitosan Schiff base （CSB） for Cr（VI） in magnetic field, the effects of the magnetic field intensity, the treatment time, the pH, value and the initial Cr（Ⅵ） mass concentration on the adsorption capacity were investigated. The results show that the saturated adsorption capacity of CSB for Cr（Ⅵ） increases to 0. 93 mg/g, while that of CTS is only 0. 34mg/g, and the corresponding time cost decreases from 120min to 60rain. It is thus concluded that magnetic field treatment improves the adsorption properties of both CTS and CSB.

Key words: ehitosan, chitosan Schiff base, chrome ion, adsorption, magnetic field
