The simultaneous removal of different types of pollutants is extremely challenging for environmental and material science.
Water dispersible magnetite-chitosan reduced graphene oxide (MCRGO) submicron particles were synthesized and
combined with positively charged porous silicon nanoparticles (PSi NPs) mainly through electrostatic interactions for the
simultaneous removal of toxic heavy metals and anionic detergent pollutants, organic dye and pesticide as well. PSi NPs
offer great potential for the simultaneous removal of inorganic and organic compounds due to their ability for adsorbing
hydrophobic and hydrophilic compounds, and other negative charged materials, on their internal and external surface. The
MCRGO hybrids showed high binding capacity for positive charged heavy metal ions and were easily separated by an external
magnetic field. Here, we report the combination of MCRGO and PSi NPs as an efficient biocompatible platform for complete
elimination of toxic heavy metals cadmium (Cd2+) and lead (Pb2+) as well as the anionic C12H25SO4
- from sodium dodecyl
sulfate (SDS) water solutions, and dye oil red O and pesticide by adsorption. Overall, the combination of MCRGO and PSi
NPs holds great potential for complex waste water treatment beyond multiple heavy metals, detergent and pesticide based
pollutants.
