摘要
叙述了以F127和CTMABr为模板剂,添加扩孔剂1,3,5三甲苯(TMB)经水热法合成不同孔径的巯基(-SH)修饰的新型介孔吸附剂。指出,以Cu+2和Pb+2为处理对象,根据不同孔径的介孔吸附剂对重金属离子的吸附性能,确定扩孔剂TMB投加量为TMB和表面活性剂摩尔比为1.5时,可得到重金属吸附的适用吸附剂的扩孔功能化硅基介孔材料,其BET孔径为6.554 nm,BET孔容为0.6134 cm3/g。
This paper describes the F127 and CTMABr as the template,add the expanding agent 1,3,5-trimethylbenzene（TMB） by hydrothermal synthesis with different pore sizes of the thiol（-SH） modified a new type of mesoporous adsorbents.Points out that the Cu＋2 and Pb＋2 was treated,depending on the diameter of the mesoporous adsorbent adsorption of heavy metal ions to determine the expanding agent dosage TMB and surfactant molar ratio of 1.5,can be adsorbent for heavy metal adsorption by the reaming function mesoporous materials,the BET pore size of 6.554 nm,BET pore volume of 0.6134 cm3/g.
