|abstract: ||The magnetic removal of Hg2+ from water has been assessed using silica coated magnetite particles. The
magnetite particles were first prepared by hydrolysis of FeSO4 and their surfaces were modified with
amorphous silica shells that were then functionalized with organic moieties containing terminal dithiocarbamate
groups. Under the experimental conditions used, the materials reported here displayed high
efficiency for Hg2+ uptake (74%) even at contaminant levels as low as 50 lg l 1. Therefore these eco-nanomagnets
show great potential for the removal of heavy metal ions of polluted water, via magnetic
