The technique for environmental protection from heavy metals is proposed in this paper. The objective of this research is development of utilization technology of metal-containing hazardous sewage with the reception of anticorrosive pigments. Zinc containing model solutions and waste water were used for this study. Cobalt was used as a cation chromophore. The method of potentiometric titration has been applied for research of precipitation process. X-ray phase analysis, electron microscopy, derivatograph method, power dispersion spectrometry, and spectrophotometric methods were used to learn the pigment properties.
