Removal of heavy metal ions from aqueous solution using Fe3O4–SiO2-poly(1,2-diaminobenzene) core–shell sub-micron particles

[Display omitted] ► Fe3O4–SiO2-poly(1,2-diaminobenzene) core–shell sub-micron particles were prepared. ► They could effectively adsorb As(III), Cu(II), and Cr(III) from solutions. ► The data fitted well with Freundlich and two-site pseudo-second-order models. ► Their stability and magnetic recovery...
