In this article examined the heavy metals ions and their ability to slow down the corrosion process also the impact of ambient temperature on their effectiveness. Solving the problem of corrosion will reduce the impact of large industrial enterprises on the environment and minimize the economic costs. To do this, plants should create a system without a discharge of waste water that is closed recycling systems, which result is a significant reduction in intake of fresh water from natural sources.For research in this paper was used Kyiv tap water and heavy metal salts.Evaluation of corrosion resistance carried out by polarization using a polarization resistance R5126 indicator and sensor electrode from corrosion indicator install UK-2 steel electrodes 20.Among all of the ions in the degree of protection against corrosion were the best ions Zn2+, Pb2+, Cr3+.In this article also studied the effect of temperature on corrosion inhibitors. Studies have shown that slow down corrosion process using ions of heavy metals at 30–50 °C slightly worse.In the future we plan to continue to investigate the influence of ions of heavy metals on corrosion processes, test their effectiveness in the composition of scale formation stabilizers such as OEDP and ATMP. Also examine the impact of these substances on bioaccumulation.
