Сomposite inhibitors for water treatment systems of the Navoi Mining and Metallurgical Combine

The reaction of obtaining the copper-zinc complex of HEDP in the presence of glycerol and EPA was studied in various ratios of the initial reagents. The dependences between effectiveness of inhibiting and ratio of Cu: Zn in obtained products is studied, it is established that copper-zinc complexates protect the metal from corrosion by more than 90% effect. It is established that due to synergistic properties in compositions with hydrolyzed acrylonitrile of copper-zinc complexonates HEDP, they effectively inhibit the vital activity of microorganisms and accordingly, biofouling, while increasing the efficiency of inhibition of scaling and corrosion by 2-4 times, thereby proving the synergistic effect
