Abstract
The effect of high-molecular surfactants on the analytical signal and the correctness of the determination of heavy metals were evaluated. It is shown that the presence of cationic and nonionic flocculants reduces the intensity of the analytical signal, while in the case of anionic the opposite situation is observed.It has been shown that the presence of high-molecular surfactants does not cause the occurrence of a systematic error in the determination of zinc, cadmium and lead.
