The synthesis of magnetite nanoparticles and their applications after surface modification have drawn in the eye of researchers toward it all through the previous a few times. In the present study, the synthesis of citric acid-modified magnetic nanoparticles has been reported. Numerous technical approaches such as x-ray diffraction, field emission scanning electron microscopy, thermogravimetric analysis and fourier transform infrared spectroscopy were accustomed to characterize these synthesized magnetite nanoparticles. The main emphasis of this examination was to study the adsorption behavior of these synthesized nanoparticles for ciprofloxacin drug from aqueous solution. The influences of various experimental parameters including pH, the contact time, amount of nanoparticles and initial concentration of ciprofloxacin drug, were investigated simultaneously. Moreover, isotherm study was observed to follow Langmuir isotherm model and the value of maximum adsorption capacity was 20.65 mg/g as calculated. Furthermore, the kinetic study was found to fit well with pseudo-secondorder kinetics model. The overall study suggested that these functionalized magnetite nanoparticles can be utilized as a proficient tool for the adsorption of drug from aqueous solution. The antibacterial behavior of these drug loaded nanoparticles was also scrutinized.
