•A mesoporous nanocomposite was synthesized and characterized by different techniques.•Fe3O4@ZrP nanocomposite was evaluated for the removal of Hg2+.•The saturation magnetization of Fe3O4@ZrP was observed 62.4emu/g.•The maximum monolayer adsorption capacity was 181.8mgg−1 at 25°C.•The tests showed high adsorption performance, high capacity and regeneration efficiency.
A mesoporous magnetic zirconium phosphate was prepared for the removal of Hg2+ from aqueous medium. The saturation magnetization of pure Fe3O4 and Fe3O4@ZrP was observed 82.9 and 62.4emu/g, respectively. The effect of different adsorption parameters was studied. The kinetic data were fitted to the pseudo 1st and pseudo 2nd order models whereas the adsorption process was best fitted into the pseudo 2nd order model. The adsorption isotherm could be well described with Langmuir model, with the maximum adsorption capacity of 181.8mgg−1 at 25°C. Thus, the present studies suggested that Fe3O4@ZrP have remarkable potential for Hg2+ removal from contaminated water.
