摘要
利用后修饰法合成了巯基功能化金属-有机骨架Ni-BDP-SH,并对其重金属离子吸附性能开展研究。由试验结果可知,Ni-BDP-SH对Hg(Ⅱ)具有良好的吸附效果和选择吸附性能,最大吸附量可达301.92mg/g,能在短时间内达到吸附平衡,并且Ni-BDP-SH在弱酸性和中性溶液中对Hg(Ⅱ)的吸附效果更好。
Thiol-functionalized metal-organic framework Ni-BDP-SH was synthesized by the post-synthetic modification, and the adsorption properties of heavy metal ions were studied. The experimental results shown that Ni-BDP-SH had good adsorption effect and selective adsorption performance for Hg(II). The maximum adsorption capacity could reach 301.92 mg/ g, and the adsorption equilibrium could be achieved in a short time. Ni-BDP-SH had a better adsorption effect for Hg(II) in weakly acidic and neutral solution.
