Abstract

Platinum electrodes in microcylindrical and tubular arrangements were compared as working electrodes for amperometric detection of 2-aminobiphenyl, 4-aminobiphenyl, 1-aminonaphthalene, and 2-aminonaphthalene in HPLC. Factors influencing separation efficiency are favourable for microcylindrical arrangement while tubular arrangement exhibits higher sensitivities and lower limits of detection. These are in the range of 0.0078-0.027μmolL-1 for tubular, and 0.11-0.42μmolL-1 for microcylindrical arrangement. Further, a new method with nanomolar detection limits was proposed for determination of tested compounds in urine using solid phase extraction for preliminary separation and preconcentration of the analytes.
