“…The calculation was based on a complete factor plan (CFP) type 2 2 . The plan-matrix CFP 2 2 and the results of the experiment of the sorption capacity of magnetite from the ratio of Fe (II) / Fe (III) and the equilibrium concentration of copper ions in distilled water are shown in table 1. The obtained dependence is presented in Fig.…”

Due to the growth of man-caused pollution, there is a need to use modern methods of water purification. It is advisable to use sorption methods for the extraction of heavy metals, which are considered to be particularly dangerous. It is established that sorbents based on magnetite are quite effective in the extraction of copper ions. It is shown that the sorption capacity of magnetite-based sorbents towards copper ions depends on the ratio of concentrations of Fe2+ and Fe3+ ions in the reaction mixture, and increases with increasing this indicator from 1/2 to 2. The sorption capacity of the sorbent towards copper ions increases by 4.4 times. It is shown that the efficiency of copper ions removal onto magnetite increases for sorbent modified with sodium sulfide. The proposed scheme provides the possibility of sorption treatment of large volumes of water from copper ions to the norms for the discharge of wastewater into fishery reservoirs. Post-productional magnetite is dehydrated and supplied to metallurgical enterprises for processing. The developed technology of water purification from copper ions is environmentally safe and energy efficient.

“…A peculiar feature of heavy metal ions is that they do not break down under natural conditions, but only their shape changes and accumulation in various components of the ecosystem takes place resulting in their damages (Tchounwou et al 2012;Fazzo et al 2017). Low-waste complex technologies for wastewater treatment from heavy metal ions will prevent their accumulation in surface water (Trus et al 2019b, Trus et al 2020c, Skiba et al 2018.…”

Iron is one of the most common components in water that adversely affect humans, other living organisms and parameters of water bodies. Therefore, during using and consuming natural waters, and discharging sewage into surface water bodies, it is necessary to remove iron compounds from the aquatic environment. The use of capillary materials in water purification processes is a promising area of research. Experimental data proved the high efficiency of capillary materials application, providing higher efficiency of iron ions removal from model solutions for real water sources of different origin compared with the traditional method of settling. The main advantage of the application of materials with capillary properties is the simplicity of implementation of the method and there is no need to use electricity and any additional reagents. The effect of various factors on the process of water deironing with the application of capillary materials was studied. It was found out that the density has a little effect on the process at an iron concentration range from 1 to 5 mg/dm 3 . The increase in competing ions content intensifies the process of divalent ferrous ions transition to trivalent. During the deironing of artesian water, the degree of iron removal exceeded 90 %, while the residual concentration was below the MPC.
