Sorption of amphoteric metals by a weakly alkaline anionite as studied by a paramagnetic probe

, 1999
EPR measurements show that sorption of copper aqua complexes from alkaline solutions by AN-31 anionite involves the formation of compounds that yield no EPR signal, most probably hydroxides.

MODIFICATION OF THE ORGANO-POLYMERIC ANIONITES SURFACE WITH XYLENOL ORANGE BY SORPTION

Odesa National University Herald. Chemistry, 2018
In this paper, the peculiarities of xylenol orange sorption removal with the help of organopolymeric anion exchangers AB-17-8 and Granion AWA-G1 in the static mode are studied. The state of the matrix and the surface of the organopolymeric anion exchanger granion AWA-G1 was characterized by the IR and Raman spectroscopy. It was established that at pH 5
