Abstract:
The stripping voltammetric behaviour of Ioxynil and 2-methyl-3-nitroaniline has been studied by means of a C(18) modified carbon paste electrode. The analytes are preconcentrated under open-circuit conditions (Ioxynil at pH 3.9; 2-methyl-3-nitroaniline at pH 10). For the determination of Ioxynil and 2-methyl-3-nitroaniline 0.01 mol/l HCl and 1 mol/l KOH, respectively, have been used as supporting electrolyte. Under optimized conditions detection limits up to 0.1 microg/ml Ioxynil and 0.3 microg/ml 2-methyl-3-nitroaniline have been obtained. The methods have been applied to the determination of Ioxynil and 2-methyl-3-nitroaniline in drinking water.
