FIELD: chemistry.
SUBSTANCE: polyacrylamide-based flocculant modification method includes using microwave radiation directed on the starting crystalline polyacrylamide product. The microwave radiation has the following properties: frequency 2.45 GHz, power 700 W, duration of irradiating crystals of the starting flocculant 5-7 s.
EFFECT: method creates conditions for further interaction of macromolecules with each other and increase in molecular weight thereof, which improves the process.
