Removal of Copper from Contaminated Soil by Use of Poly ...

Over 90% of copper initially sorbed in the soil was removed by use of ∼66 bed, volumes of 0.10% (,w/w) of a generation 4.5 dendrimer with carboxylate terminal groups at pH 6.0. On the basis of equal equivalent dose, dendrimers of lower generation removed more copper. Lowering pH enhanced copper removal for all dendrimers tested.
