| Description |
Preconcentration by coflotation is employed to improve
the detection limits for the determination of parts per
billion levels of heavy metal ions such as copper(II),
lead(lI), cadmium(II), zinc(II), nickel(II) and coba1t(II) in natural and sea water by differential pulse polarography
(DPP). Trace amounts of these ions in water are
coprecipitated on colloidal aluminium hydroxide and the
precipitate is floated with the aid of sodium oleate and a
stream of nitrogen bubbles. Experimental conditions are
optimized to obtain maximum recovery of these ions by
cofiotation. The effect of surfactant on the DPP peak
currents of these ions in 'the supporting electrolyte used in this work is studied.
