چکیده:

Reseach about synthesis of composite Fe-chitosan and its application for the adsorption of methylene blue and paraquat dichloride in aqueous medium have been done. Composite has been synthesis trough hydrogel formation interact with Fe solution. The characterization of composite by FTIR and EDX analysis denote the change of N-H bond length of chitosan. XRD data confirm with SEM data shown the effect in chitosan crosslink result that composite Fe-chitosan have more layer than chitosan hydrogel and stabile at 2-12 H range. Adsorption of methylene blue and paraquat dichloride from wastewater maximum at 30 minutes with adsorption capacity was 5.4×10-5 mol/g and 1.3×10-4 mol/g, respectively.
