Abstract

Section titled “Abstract”

The goal of this study was to determine benzophenone-3 at the boron-doped diamond electrode and in the presence of cetyltrimethylammonium bromide by adsorptive stripping voltammetry. The oxidation of benzophenone-3 was irreversible by differential pulse voltammetry. The peak height increased with boron concentration in the electrode film deposited as 500-8000 parts per million boron/carbon. Limits of detection of 1.5, 1.9, and 0.8 micromoles per liter were obtained for 2000, 4000, and 8000 parts per million films in Britton-Robinson buffer at pH 12.0. Positive effect of cetyltrimethylammonium bromide on the determination of benzophenone-3 includes higher sensitivity, a shift of the peak potential to less positive values, and an improved limit of detection by an order of magnitude to 0.1 micromole per liter.
