采用嫁接法合成了巯丙基官能团化介孔分子筛MCM-41(MP-MCM-41),其结构经XRD、FT-IR、热重分析、N2吸附等手段进行了表征。研究了MP-MCM-41对水溶液中Pb^2+的吸附,结果表明其具有较高的吸附量,在适宜的吸附条件下吸附量可达37.08mg/g。
In this paper, mercapto-modified mesoporous silicate MCM-41 (MP-MCM-41) was synthesized by the grafting method and characterized by XRD, FT-IR, TGA and N2 absorption. The results showed that the MP-MCM-41 exhibited remarkably high adsorption capacity for adsorption of aqueous Pb^2+ , 37.08mg/g of the adsorption capacity could be achieved at convenient adsorption conditions.
