Preconcentration of copper,cadmium, mercury and lead from sea and tap water samples on a dithiocarbamatecellulose derivative

Ethylenediamine, 2,2'-diaminodiethylamine, and triethylenetetramine (trien) were introduced onto microcrystalline cellulose after tosylation. Dithiocarbamate (DTC) groups were introduced by reaction with carbon disulphide. The metal uptake behaviour of these amine- and dithiocarbamate-cellulose derivatives were compared for Cu(II), Cd(II), Pb(II), Hg(II), Co(II), and U(VI). The trien—DTC-cellulose was used to preconcentrate Cu(II), Cd(II), Hg(II), and Pb(II) from sea and tap water.
