Cu(II), Sb(III), Bi(III), and Pb(II) were cathodically deposited to a hanging mercury drop electrode (HMDE) from a 1.0 M HCl medium in a flow cell followed by quantification by differential pulse anodic stripping voltammetry (DPASV) in a malonic acid/HCl stripping medium. Well-defined peaks were observed and peak separation of {Delta}E{sub p} > 80 mV was achieved for the four metals. This method has been applied successfully to the analysis of environmental water samples. Recovery of 100{+-}7% was obtained at 10{sup {minus}8}-10{sup {minus}9} M levels and detection limits were at the level of 10{sup {minus}10} M.
