摘要：

In this study, xantahted chitosan (CTS-X) was synthesized through a simple one-step preparation method, the analysis results of XPS and FT-IR spectra confirmed the successful introduction of xanthate. The specific surface area of CTS-X was higher than original chitosan, and the pore structure was relatively simple. CTS-X exhibited excellent adsorption performance for Sr(II). The adsorption rate of Sr(II) was fast, and the rate-limiting step was extra diffusion process. The maximum adsorption capacity was 58.36 mg g- 1, calculated by D-R isotherm model, which was higher than most chitosan-based adsorbents. The main adsorption sites were hydroxyl groups and xanthates. Due to simple preparation and excellent adsorption performance, CTS-X has potential in application for radionuclide separation from radioactive wastewater.
