dc.description.abstractThe epoxy-impregnated graphite tube electrode bulk modified with 2-mercaptobenzoxazole, employed in a wall-jet configuration, was found to be useful for the continuous flow and flow injection stripping voltammetric determinations of AgI, HgII and BiIII. For continuous flow, detection limits for AgI, HgII and BiIII were 1.8 × 10-10 M, 1.9 × 10-9 M and 9.5 × 10-9 M, respectively (10 min accumulation, S/N = 3). Precisions for 5.00 × 10-9 M AgI, 1.00 × 10-8 M HgII and 1.00 × 10-7 M BiIII were 10.5 %, 5.77 % and 7.90 % (relative standard deviations, n = 6), respectively. In the case of flow injection stripping, with a 500 μL injection loop, detection limits of 0.59 ng, 2.0 ng and 120 ng were obtained for AgI, HgII and BiIII, respectively (S/N = 3). Selected metal ions, inorganic and organic substances were investigated for interferences. The electrode was tested with a certified sample and then applied to the determinations of the metal ions in a urine and a sea-water sample.
