The voltammetric behavior of 5- nitroindazole (5-NI) has been investigated using mercury meniscus modified (m-AgSAE) silver solid amalgam electrode (inner diameter 0.5 mm). Differential pulse voltammetry (DPV) and cyclic voltammetry (CV) were used for study of electrochemical behavior of 5-NI. Britton-Robinson buffer was found to be the best available supporting electrolyte for 5-NI determination. The reaction mechanism was investigated by CV and by elimination voltammetry with linear scan (EVLS). DPV with optimized working parameters was applied for analysis of model solutions containing 5-NI. The limit of detection was calculated as 0.14 mol L for m-AgSAE. Proposed method was successfully tested for analysis of real water samples spiked by 5-NI.
