Voltammetry Study of an Anti-HIV Compound by means of a Thin Organic Membrane

International Journal of Electrochemistry, 2013
Cyclic and square wave voltammetries have been used to study electrochemical behaviour of an anti-HIV agent (Guttiferone A) at the liquid-liquid interface. The thin organic membrane is formed by an organic solvent containing redox probe. Guttiferone A, a
