Abstract

 

Aim: In this study, the adsorption ability of surface modified magnetite nanoparticles was investigated.    

 

Methodology: Magnetite nanoparticles (MNs) were prepared by solvothermal method and the surface was modified by 3-(2-Aminoethylamino) propyldimethoxymethylsilane (AEAPS) and utilized as an adsorbent against nickel ions in aqueous solution. Characteristic studies were performed to study the various properties of MNs before and after surface modification. Ni2+ adsorption was studied as a function of contact time, initial concentration and adsorbent dosage at neutral pH and constant temperature (100 ?C).    

 

Results: Presence of required characteristic peaks in IR spectrum and X-ray diffraction (XRD) patterns revealed formation of magnetite and surface modification. Spherical and defined morphology of surface modified MNs (aMNs) was studied through electron micrographs. The kinetic data obeyed the first-order equation.    

 

Interpretation: Surface modified MNs can be used for the efficient removal of Ni2+ from aqueous solution. Also, the kinetics study revealed the adsorption capacity of MNs against nickel ions.

 

Key words: Adsorption, Kinetics, Magnetite, Nanoparticles, Nickel ions
