Novel alginate-chitosan amine-functionalized silica coated magnetic composite for heavy metals removal in water

A new effective biopolymer alginate chitosan amine-functionalized silica coated magnetic composite (alg/Cs-NH2-SiO2/Fe3O4) adsorbent was synthesized and applied for the first time to remove Pb(II), Cu(II) and Cd(II) from aqueous solution by utilizing inductive coupled plasma-optical emission spectro...
