Arsenite determination in phosphate media at electroaggregated gold nanoparticle deposits

Abstract:

Compared to bulk gold, highly reactive mesoporous gold film deposits are prepared on a boron-doped diamond electrode surface. An electroaggregation process causing 5 nm diameter gold nanoparticles to deposit cathodically from aqueous solution is implemented to control the amount of mesoporous gold at the electrode surface. The resulting electrode surface is characterized by electron microscopy and by cyclic voltammetry. The reactivity of the electroaggregated gold deposit towards arsenite is ...
