FIELD: chemistry.
SUBSTANCE: flocculant for water purification is obtained by copolymerisation of a monomer mixture - itaconic acid or its anhydride, alkyl ether of itaconic acid and amide of acrylic or methacrylic acid, with content of each component in a mixture equal to 10-80 mol.%. As amides of acrylic or methacrylic acid used are: acrylamide, methacrylamide, N-alkylacrylamide. It is possible to perform copolymerisation in the presence of a solvent.
EFFECT: simplification of the process technology, increase of qualitative characteristics of the flocculant, used for purification of water, which has different values of acidity, salinity, concentration of wide spectrum of pollutants; the flocculant also has low production cost.
