制备了具有均匀介孔的硫醇和氨基功能化的SBA-15二氧化硅，并将其用于去除废水中的重金属离子；硫代化的SBA-15对Hg2+表现出较高的络合亲和力，而其他金属离子(Cu2+、Zn2+、Cr3+和Ni2+)与其胺化类似物表现出良好的结合能力。
Thiol- and amino-functionalized SBA-15 silicas with uniform mesoporosities were prepared and employed for removing heavy metal ions from waste water; the thiolated SBA-15 adsorbent exhibited a higher complexation affinity for Hg2+, while the other metal ions (Cu2+, Zn2+, Cr3+ and Ni2+) showed exceptional binding ability with its aminated analogue.
