| 제목 | Adsorption of hexavalent Chromium ions from aqueous solution with amine-functionalized nonporous and mesoporous silica nanoparticles with uniform nanopores |
| 초록 | Silica is a mineral commonly found in nature and has been widely employed in industrial fields. In particular, amorphous silica nanoparticles (ASNs) are one of the most common nanomaterials being used in many applications because of their good biocompatibility, facile synthesis procedure, relatively easy surface modification. They are also being developed for various biomedical and pharmaceutical applications such as drug delivery and therapy, multifunctional bio-imaging probes, etc. We are developing synthetic methods to prepare amine functionalized ASNs in order to use them to remove hexavalent Chromium ions from wastewater. We demonstrate highly monodispersed ASNs with average size 20 nm are obtained from our method. Furthermore, our method allows ASNs can be produced with uniform nanopores formed inside the nanoparticles developing a high specific surface area. As-prepared ASNs and nanoporous. |
