Abstract

A highly flexible, automatic sequential-injection stripping analysis (SISA) system has been developed and applied for monitoring the levels of mercury in aqueous solutions using a chemically modified electrode. The preparation of the modified electrode comprises spin coating of an ethanolic solution of poly(4-vinylpyridine) and Kryptofix-222 onto a glassy carbon electrode (GCE) followed by cross-linking the polymer. The analysis is based on the anodic stripping voltammetry of mercury using differential pulse voltammetry. A sequence of 36 operations was needed to complete a full cycle of cleaning, calibration and analysis.
