Abstract

The authors derivatize C powder with anthracene, azobenzene, diphenylamine, 9,10-diphenylanthracene, methylene blue, 3-nitrofluoranthene, 6-nitrochrysene, 9-nitroanthracene, 9,10-phenanthraquinone (PAQ), thionin, and fast black K (2,5-dimethoxy-4-[(4-nitrophenyl)azo]benzenediazonium chloride) and sep. immobilize the resulting material onto a bppg electrode. The authors use cyclic voltammetry (CV) to demonstrate that the obsd. voltammetric response for each derivatized C is consistent with that of an immobilized species. Further, the authors use CV and square wave voltammetry (SWV) to study the effect of pH on the peak potentials of each compd. studied over the range pH 1-12 and at elevated temps. up to 70° to demonstrate the versatility of derivatized C electrodes as reagentless pH sensors.
