FIELD: chemistry.
SUBSTANCE: invention relates to a process of production of magnetic sorbents. The sorbent comprises humic acids as a polymeric binder and a magnetic filler comprising magnetite. The size of magnetite particles is 7-30 nm. The magnetite:humic acid ratio is from 1:4 to 4:1. The efficiency of aquatic environment decontamination by introducing the sorbent depends on the nature of contaminants and amounts to 97-100%.
EFFECT: product possesses magnetic properties and high sorption capacity.
