Preparation of Thiol/Oxidized Cellulose Adsorbent and Selective Adsorption of Ag(Ⅰ) in Chlorination System

Keywords： Ag(Ⅰ) chloride anion , cellulose , chlorination liquid , selective adsorption

以废纸纤维素为原料,将纤维素氧化开环胺化后再进行巯基化反应,制备得到了一系列巯基修饰的纤维素类吸附剂.研究发现,无论是单一氯化体系还是高铜高镍氯化混合体系,基于氨基硫脲修饰戊二醛交联的氧化纤维素吸附剂对配阴离子AgCl43-的吸附效果最好,最大吸附量可达到171.16 mg/g.通过红外、X射线光电子能谱、热力学等技术手段分析探讨了其不同吸附效果的原因及该吸附剂对配阴离子Ag(Ⅰ)的静电引力吸附机理.
