Optimization of dose calculation of modified magnetite during sorption purification of water from copper ions to create environmentally friendly technology

Abstract: 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 in… Show more

“…The calculation was based on a complete factor plan (CFP) of type 2 2 [36]. The plan-matrix of CFP 2 2 and the results of the experiment of residual concentrations of sulfates in water depending on the dose of lime and sodium aluminate are shown in table 2.…”

“…This complicates the water purification technology. The filtration of water through the magnetite layer is too slow, as the magnetite particles are very fine (they are nanoparticles in size) [34]. Therefore, magnetitemodified cation exchange resins, such as KU-2-8 cation exchange resin, are used to remove magnetite under dynamic conditions.…”
