Abstract
In the present study, cellulose nanoparticles modified with folic acid were synthesized and characterized using some instrumental techniques such as elemental analysis, scanning electron microscopy (SEM) and FTIR. The modified cellulose nanoparticles were employed for removal of Al3+, Cr3+ and Fe3+from aqueous solution. Someimportant parameters such as pH, adsorbate concentration, temperature and adsorption times were studied to estimate the optimum adsorption condition. According to results, adsorption kinetics followed the second-order kinetic model indicating that the chemical adsorption is the rate limiting step. Also, Langmuir model showed the best fit in adsorption isotherm experiments with maximum adsorption capacities of 88, 68 and 56 mg/g for Fe3+, Al3+ and Cr3+with cellulose nanoparticles modified with folic acid .An analytical applications of the present method compared with the solvent extraction method to real samples containing Al3+, Cr3+ and Fe3+were used and the results were satisfied.
