Abstract

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.

期刊介绍： Progress in Nuclear Energy is an international review journal covering all aspects of nuclear science and engineering. In keeping with the maturity of nuclear power, articles on safety, siting and environmental problems are encouraged, as are those associated with economics and fuel management. However, basic physics and engineering will remain an important aspect of the editorial policy. Articles published are either of a review nature or present new material in more depth. They are aimed at researchers and technically-oriented managers working in the nuclear energy field. Please note the following: 1) PNE seeks high quality research papers which are medium to long in length. Short research papers should be submitted to the journal Annals in Nuclear Energy. 2) PNE reserves the right to reject papers which are based solely on routine application of computer codes used to produce reactor designs or explain existing reactor phenomena. Such papers, although worthy, are best left as laboratory reports whereas Progress in Nuclear Energy seeks papers of originality, which are archival in nature, in the fields of mathematical and experimental nuclear technology, including fission, fusion (blanket physics, radiation damage), safety, materials aspects, economics, etc. 3) Review papers, which may occasionally be invited, are particularly sought by the journal in these fields.
