Abstract :
In this study, a modified chitosan transparent thin membrane (MCTTM) was prepared and used for transition metal ions removal from aqueous solutions. The physical and chemical characteristics of the MCTTM were characterized by X-ray diffraction (XRD) and Thermal Gravity Analysis (TGA). The characterization of color changes of the MCTTM after adsorption shows that the MCTTM has the potential to detect some transition metal ions in aqueous solutions rapidly.
