| Abstract: | In this work, the adsorption properties of crosslinked chitosan for Mo(VI) were studied. The adsorption rate of Mo(VI) by CCTS was 97% at pH 3.0. Adsorption balance time, elution conditions, the effect of coexisting elements, and the adsorption mechanism were investigated. A novel method of ultratrace Mo(VI) preconcentration with CCTS and determination by graphite furnace atomic absorption spectrometry was found. The detection limit (3σ, n = 10) of the method was 0.040 μg L?1, and the relative standard deviation was 2.98% at 1.00 μg L?1. The method has been applied to the determination of Mo(VI) in environmental water samples, with satisfactory results. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 101: 432–435, 2006 |
