Abstract
An automated method for the determination of mercury (II) with chemilu minescent detection is proposed. The system is based on the inhibitory action of mercury on enzymic activity of alcohol oxidase. When alcoho l oxidase is in presence of mercury, its activity decreseases; this ca uses a decrease of hydrogen peroxide production, which is monitored by the luminol chemiluminescence and correlated to the concentration of mercury in the solution. The determination range was 10-100 ppm, and t he throughput was 24 samples/hour.
