The presence of micellar systems allows one to eliminate the previous solvent extraction step that is necessary for the determination of metal–DDTC complexes in the absence of micelles. This reduces the cost and toxicity of the method. The influence of anionic micelles on the analytical characteristics (sensitivity and detection limits) was studied. The proposed method was applied to the determination of CuII in industrial waste water and in nickel covered metallic samples, and the results were compared with those obtained by flame atomic absorption spectrometry.
