A slurry suspension sampling technique is developed and optimized for the rapid microextraction of heavy metals and analysis using nanometer-sized ceria-coated silica-iron oxide particles and inductively coupled plasma optical emission spectrometry (ICP-OES). Magnetic-silica material is synthesized by a co-precipitation and sol-gel method followed by ceria(More)
Cotton fibers were functionalized, following the coating of fibers with graphene oxide (GO), the covalent attachment of aminosilica nanoparticles and the reduction to the cotton-GR-aminosilica material. Employing the cotton-supported graphene (GR)-aminosilica material, a novel and easily applicable extraction mode was put forward. Several groups of analytes(More)
