The use of metal galvanic zinc coatings for protection against corrosion reaches broad indicators due to their obvious advantages: simplicity of preparation, low cost, environmental friendliness, and a long period of resistance to the effects of an aggressive environment on the coating. Sulfuric electrolytes of galvanizing containing a complex of SAS used in combination with each other were investigated. Their effective influence on the protective properties and appearance of zinc coatings is shown. The qualitative and quantitative composition of zinc coatings on a JSM-6490LV raster electron microscope with the systems of energy dispersive microanalysis of INSAEnergu and HKL - Basicc structural analysis with a useful magnification of 300,000 was investigated. Obtained non-porous, fine-crystalline, dense, bright galvanic zinc coatings from electrolytes with surfactants with good adhesion to the base, a comparison of their quality is given, conclusions are made.

Laboratory results of biological sewage treatment from ions of heavy metals and synthetic surface-active substances are discussed in this article. The data on dependence of cleared sewage’s qualitative and quantitative composition from the mixture sequence of sewage’s separate streams are obtained as a result of researches. Results on research of specific adsorption of metals by activated sludge biomass are presented. The estimated prevented ecological damage from dumping of polluting impurity to the river is calculated.

To receive monosized goethite (α-FeOOH) nanoparticles powders in the process of chemical precipitation of iron salt and alkali various surface active substances (SAS) with concentration of 0.3% were added to water: C12H25NaO4S (anion active), C12H38ClN (cation active) and EDTA – C10H14O8N2Na2 (complexon). It has been determined that the magnetic properties of the nanoparticles under investigation change in comparison with the nanoparticles obtained without SAS addition. In all the samples under study very interesting saturation magnetization temperature dependences have been obtained. They indicate the difference in goethite temperature phase transformations connected with various surface layers formed on the nanoparticles under SAS influence.
