Electrocatalytic Determination of Ammonium dinitramide Using Carbon past Electrode Modified with CdO nanoparticles

摘要: Ammonium dinitramide (ADN) is emerging as a promising candidate to replace conventional ammonium perchlorate in solid propellants [1, 2]. The electrochemical behavior and ability of a carbon paste electrode modified with CdO nanoparticles (CdONCPME) as a potential electrocatalyst for the reduction of ADN was investigated using cyclic voltammetry (CV) and chronoamperometry. The CdONCPME exhibited a good electrocatalytic activity toward the reduction of ADN in 0.1 M phosphate buffer solution (pH= 4). The diffusion coefficient of ADN and rate constant for the catalytic reaction were also evaluated. This study is a continuation of developing a rapid and inexpensive electroanalytical method for the determination of AND in real samples.
