Adsorptive Stripping Square-Wave Voltammetry of Creatine [PDF]

Analytical Letters, 1999
ABSTRACT An adsorptive stripping square-wave voltammetric method for quantitative determination of creatine is developed. The basic redox properties of creatine are investigated by means of square-wave and cyclic staircase voltammetry. Creatine undergoes an irreversible reduction in neutral and acidic medium at a hanging mercury drop electrode.
