摘要

Interdigitated arrays of microband electrodes are used for highly sensitive anodic stripping with collection experiments, Compared to analogous experiments at rotating ring-disk electrodes, the interdigitated microelectrode array offers high collection efficiencies and the use of quiescent solutions. New lithographically fabricated carbon band microelectrodes, made by pyrolysis of 3,4,9,10-peryleneterracarboxylic dianhydride, are employed for supporting the mercury film. Metal cations stripped from one microband electrode diffuse across the narrow gap and are redeposited (collected) at the second electrode, kept at a suitable negative potential. The elimination of the charging current (accrued from the fixed collection potential) results in well-defined peaks, superimposed on a constant background, and hence in a greatly improved detectability. Experimental variables affecting the collection efficiency and the response, including the gap and scan rate, are examined. [References: 15]
