V. V. Siyanitsa, V. M. Kochkodan, V. V. Goncharuk
Pages: 467-472


A process of ultrafiltration purification of water solutions from copper ions with addition of polymer chelating agents of various chemical nature (polyethyleneimine, poly(diallyl dimethylammonium chloride), dextrane, humic acids) has been explored. A possibility to perform a recovery of Cu2+ polyethyleneimine complex with the aim to re-use the chelating agent has been demonstrated.
