Preparation and characterization of magnetic chitosan and its application for preconcentration of platinum(IV) metal ions

Magnetic chitosan beads were prepared by 3 different weight ratios of Fe3O4 : chitosan, i.e. 1:1, 5:1 and 10:1, and were cross-linked with glutaraldehyde. Physical characterizations of the beads were carried out by scanning electron microscope (SEM), image analyzer, Fourier transformed infrared spec...
