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Pb2+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。
The mercaptopropyl-functionalized mesoporous molecular sieve MCM-41 (MP-MCM-41) was synthesized by grafting method. Its structure was characterized by XRD, FT-IR, TG and N2 adsorption. The adsorption of Pb2 + by MP-MCM-41 on aqueous solution was studied. The results showed that the adsorption capacity of Pb-MP-MCM-41 was higher than that of MP-MCM-41 and the adsorption capacity was 37.08 mg / g under appropriate adsorption conditions.
