Dinoseb, systematically 2-(1-methylpropyl)-4,6-dinitro-phenol, is phenolic, commonly used herbicide and insecticide. Dinoseb has two very easy reducible nitro-groups in its structure and one electrochemically oxidizable hydroxy group. Differential pulse voltammetry was applied for its determination in water. The nitro group reduction was used for voltammetric determination with hanging mercury electrode (HMDE), mercury film electrode (MFE) and modified carbon paste electrode (MCPE) and carbon paste electrode (CPE) as well as meniscus modified silver solid amalgam electrode (m-AgSAE).
