Chromium removal from industrial water through functionallized nanoparticles.
Cr ion-polluted industrial water was treated with commercial activated carbon and with either mercaptane- and amine-functionallized silica nanoparticles, revealing that the use of relatively low surface area materials can advantageously compete with high surface area materials, traditionally utilized for removing hazardous metal ions, provided a proper surface functionalization of the nanoparticles is in place. FTIR and SEM characterization of the different materials and stages of the experiments are provided, as well.
