- Abstract:
-
The electroanalytical detection of trace mercury(II) at gold ultra-microelectrode arrays is reported. The arrays consist of 256 gold microelectrodes of 5 μM in diameter in cubic arrangements which are separated from their nearest neighbor by 100 μm. The array was utilized in nitric acid using linear sweep voltammetry where a linear response from mercury additions over the range 10 μg L-1 - 200 μg L-1 (10 -8 - 10-6 M) was observed with a sensitivity and detection limit of 0.11 nC/μg L-1 and 3....
