Description
Summary:Malar et al discuss their study which examines the adsorption ability of surface modified magnetite nanoparticles. 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. Ni adsorption was studied as a function of contact time, initial concentration and adsorbent dosage at neutral pH and constant temperature. They conclude that surface modified MNs can be used for the efficient removal of Ni from aqueous solution. Also, the kinetics study revealed the adsorption capacity of MNs against nickel ions.
