Abstract

Uranyl, UO₂²⁺, was electrochemically determined by a phosphate based self-assembled monolayer. A pretreated gold electrode with 2-mercatpoethanol was chemically modified by POCl₃ or POBr ₃ to obtain the surface phosphate active sites. The different stages were characterized by reflection-absorption Fourier transform-infrared (FT-IR) spectroscopy, capacity, and X-ray photoelectron spectroscopy (XPS). The electrochemical determination of UO₂²⁺ was accomplished, after preconcentration under open circuit potential, by square wave voltammetry.
