Electrooxidation of thiourea and its square-wave voltammetric determination using pencil graphite electrode

Reviews in Analytical Chemistry, 2011
The electrochemical properties of thiourea (TU) were investigated in pH range 2.0–12.0 by cyclic and square-wave voltammetry. The compound was irreversibly oxidized at a pencil graphite electrode in one or two oxidation steps which are pH-dependent ...
