Notes:
Flow-injection analysis (FIA) with voltammetric detection can be used in either the direct voltammetric or the stripping mode. In this study, a locally designed and constructed instrument with features not available in commercial instruments was used for the precise analysis of silver in aluminum. The carrier solution was 0.1 M Al(NO3)3 with 2 × 10-3 M HNO3. Silver solution was introduced by timed, partial-loop injection. After cathodic deposition, a square-wave or staircase voltammetric stripping sweep was applied. The data were recorded and analyzed by computer. Silver solutions of 8 × 10-8 to 4 × 10-5 M were tested. The standard deviations of repeat determinations of artificial samples varied from 0.12 to 0.78%. This precision was limited by the stability of the pump flow.
