In this article, an assay of trace cobalt ion was searched by using carbon nanotube paste electrode (PE).
Under optimized analytical conditions, linear working ranges were from 70 to 700 ngL^(-1) measured with SW stripping voltammetry, from 70 to 910 mgL^(-1) with chronoamperometry. A relative standard deviation (RSD)of 20.0 mgL^(-1) Co (II) was of 0.12% SW (n = 15). Detection limit was attained as 7.93-ngL^(-1) (1.3×10^(-10) M Co(II). Here analytical application was performed to in vivo implanted living fish brain and a dissolved fish kidney tissue was also used for diagnostics. Moreover, the patch-type electrode system was applied to plant or leaf skin assay. The developed methods can be applied to in vivo direct assays for real time monitoring with optimum parameters. |
