| Abstract: | A flow-through voltammetric cell is described and the d.c. and pulse working modes are studied in on-line situations. On-line analysis of different compounds has been done by (a) direct oxidation at a glassy carbon electrode, (b) direct reduction or (c) direct oxidation at a mercury-coated solid electrode, and (d) cathodic stripping by first depos-iting the compound on a mercury film and then employing a cathodic d.c. voltage scan. The linear range and the detection limit of the on-line method are better than those in quiescent solutions |
