Магнитный композиционный сорбент по п.1, отличающийся тем, что соотношение наночастиц магнетита и гуминовых кислот составляет от 50 до 80 масс.% в составе композита.3. Магнитный композиционный сорбент по п.1, отличающийся тем, что в качестве магнитоактивного компонента используют магнетит в виде суспензии с размерами частиц от 7 до 30 нм.4. Магнитный композиционный сорбент, отличающийся тем, что его получают механохимическим синтезом путем диспергирования в шаровой мельнице наночастиц магнетита и гуминовых кислот или солей гуминовых кислот при соотношении компонентов, указанных в п.2.1. The magnetic composite sorbent for purifying polluted waters from heavy metals and radionuclides includes, as components, FeO magnetite nanoparticles synthesized in a matrix of a natural polymer binder, which are used as multifunctional humic acids. 2. The magnetic composite sorbent according to claim 1, characterized in that the ratio of magnetite nanoparticles to humic acids is from 50 to 80 wt.% In the composition of the composite. The magnetic composite sorbent according to claim 1, characterized in that magnetite is used as a magnetoactive component in the form of a suspension with particle sizes from 7 to 30 nm. Magnetic composite sorbent, characterized in that it is obtained by mechanochemical synthesis by dispersing in a ball mill nanoparticles of magnetite and humic acids or salts of humic acids at a ratio of the components specified in paragraph 2.
