Abstract
Poly(N-vinyl 2-pyrrolidone) (PVP)/acrylonitrile (AN) interpenetrating polym er networks (IPNs) were synthesized and amidoximated for the purpose of ura nyl ion adsorption. The adsorption of amidoximated IPNs was studied from di fferent uranyl ion solutions (850, 1000, 1200, 1400, and 1600 ppm). The res ult of all our adsorption studies showed that the bonding between UO22+-ami doxime groups complied with the Langmuir-type isotherm. The adsorption capa city was found as 0.75 g UO22+/g dry amidoximated IPN. In order to increase the UO22+ ion adsorption capacity the amidoximated IPN was treated with al kali, but no significant increase could be observed. (C) 2001 John Wiley & Sons, Inc.
