In our study, cellulose nanoparticles customized with tetracycline were produced and characterized by several instrumental techniques such as scanning electron microscopy (SEM), elemental analysis and FTIR. The modified cellulose nanoparticles were employed for removing of and from aqueous solution. Effect of several essential parameters including temperature, pH, adsorption instances and adsorbate concentration had been examined to evaluate the optimum adsorption condition. Chemical adsorption as the rate limiting step was confirmed, where the adsorption kinetics followed the second-order kinetic model. Also, the adsorption isotherm experiments showed the best fit with Langmuir model with maximum adsorption capacities of Cu2+, Cd2+ and Pb2+with cellulose modified with tetracycline. Comparing to the solvent extraction method an analytical applications of the present method to real samples containing were used and the results were good satisfied.
