description

A method for determination of 2,5-dimethylaniline is proposed. The procedure enables both spectrophotometrical and voltammetric measurements. The spectrophotometrical determination at λmax = 385.8 nm is possible for concentrations up to 1.25 × 10-6 mol l-1. The voltammetric method takes more time, however, due to the adsorptive enrichment of the substrate it is possible to determine concentrations in the range of 10-7 mol l-1). In the paper the optimal conditions and parameters for the determination are suggested.
