Aqueous “Polysulfide-ene” Polymerization for Sulfur-Rich Nanoparticles and Their Use in Heavy Metal Ion Remediation |
| 초록 |
Recently, there has been interest in decontamination of heavy metal in water to protect public health. Especially, in spite of global technological and regulatory effort, the amount of mercury in shallow part of the ocean has been tripled since industrial revolution. Previously reported mercury adsorbents suffer from low mercury removal capacity, sophisticated preparation steps, and expensive raw materials. Exploiting high affinity of sulfur for “soft” metal ions such as mercury is one of the promising method. However, the direct use of elemental sulfur as adsorbent for use in water has been limited to sulfur impregnated activated carbon. Here in, we report a facile method for the synthesis of high sulfur content nanoparticles and its thiol-functionalization with investigation into the mercury removal capacity. Furthermore, adsorption capacity on various metal ions and investigation at harsh conditions were explored for creating viable option for real-world applications. |
