Hematite nanoparticles have been functionalized with a self-assembled monolayer of undecanoic acid (UA) by covalent attachment via siloxane groups. The number density of carboxylic/carboxylate groups on the surface was determined by titration, yielding values on the order of 10 ¹⁴ UA molecules/cm ² and thus consistent with a closed-packed monolayer. The ability of these functionalized particles to adsorb Cd ²⁺ in the ppm range was demonstrated using in situ anodic stripping voltammetry.
