| Summary: | <p>The synthesis of new thiourea derivative of chitosan and its characterization by Fourier transform infrared spectroscopy (FT-IR) and X-ray diffraction (X-RD) is described. The thiourea derivative of chitosan, were prepared by adding an acetic acid solution of chitosan into aqueous solution of thiourea. An insoluble thiourea chitosan were obtained after an exess adition of NaOH. The adsorption capacity of the product for cadmium (II) and nickel (II) were tested at several metal concentrations of different values of pH. A Langmuir model for adsorption isotherm is applied for comparing the adsorption properties of the two metals investigated.</p> |
