文摘

Two Re adsorbents were synthesized by grafting of vinylimidazole and vinylpyridine onto silanized silica gel via γ-radiation. The Re adsorption capacities of SS-MPTS-VIMH and SS-MPTS-VPQ were 145.99 mg g−1 and 71.08 mg g−1, respectively. Both the adsorbents had fast adsorption kinetics, and could be used for column adsorption. SS-MPTS-VPQ had good anti-interference abilities, and might be used for the disposal of Tc in the future.
