We present a new organic-inorganic hybrid particles as an adsorbent.
Hyperbranch-like amphiphilic polymers is conjugated onto silica nanoparticles.
The particle removed phenolic compound and azo dye from aqueous solution.
The particle was easily separated type the treated water due to density difference.
The particle is a promising sorbent for hydrophilic and/or hydrophobic pollutants.
