Abstract
- A grafting process has been found to be effective in producing sieves that bind quantitatively more heavy metal ions than standard techniques. The sieves were made using covalent grafting of 3-mercaptopropylsilyl groups MCM-41 and HMS to the framework pore walls. The functionalized HMS derivative has found to bind more mercury (II) ions than the initially anionic MCM-41 derivative.
