| titleOfInvention | Method of obtaining anion exchanger |
| abstract | The invention relates to a process for the preparation of anion exchange materials and can be used for the sorption, separation and concentration of metals and the purification of industrial wastewater. The invention makes it possible to increase the sorption capacity of anion exchangers (ESR, mEq / g: by Cu 5.3-6.0, by Ni 3.2-5.9) due to the fact that polyethylene polyamine (PEPA) with mol.m. 290 or polyethyleneimine (PEI) mol. 1-10 is reacted with epoxy toluene-phenol-formaldehyde oligomer (ETFFO) with mol. 516 and an epoxy content of 12.3 wt.% with a mass ratio of PEPA. or PEI: ETFFO of 0.75-2.5: 1, for 15 minutes, followed by curing at 80 ° C for 10 h and then at 100 ° C for 10 h.
