The catalytic abilities of gold electrode were tested for the quantitative  determination of amphetamine (A) and 3,4-methylenedioxy-N-methylamphetamine  (MDMA) standards by their oxidation using cyclic voltammetry (CV). The value  of the oxidative currents of A and MDMA standards at 0.80 V vs. SCE in 0.05 M  NaHCO3 at the scan rate of 50 mV/s is linear function of concentration in  range of 110.9-258.9 mM and 38.7-229.2 mM, respectively. Square wave  voltammetry (SWV) revealed linear increase of current with concentration of  MDMA (range 30.9-91.6 mM) and thus quantitative determination of amphetamine  derivates. SWV analysis is successfully performed in spiked urine samples as  well. A and MDMA in the presence of sucrose and as a content in illegally  produced tablets were also analyzed. The voltammetric determination of A and  MDMA derivatives using CV and SWV at gold electrode is a rapid, selective and  simple procedure and its accuracy was confirmed with reference method, high  performance liquid chromatography (HPLC). The spiked urine samples analysis  offers additional possibility for the rapid detection of A and MDMA in human  urine
