Abstract
Poly(N-vinyl 2-pyrrolidone) (PVP)/acrylonitrile (AN) interpenetrating polymer networks (IPNs) were synthesized and amidoximated for the purpose of uranyl ion adsorption. The adsorption of amidoximated IPNs was studied from different uranyl ion solutions (850, 1000, 1200, 1400, and 1600 ppm). The result of all our adsorption studies showed that the bonding between UOurn:x-wiley:00218995:media:APP1673:tex2gif-stack-2-amidoxime groups complied with the Langmuir-type isotherm. The adsorption capacity was found as 0.75 g UOurn:x-wiley:00218995:media:APP1673:tex2gif-stack-3/g dry amidoximated IPN. In order to increase the UOurn:x-wiley:00218995:media:APP1673:tex2gif-stack-4 ion adsorption capacity the amidoximated IPN was treated with alkali, but no significant increase could be observed.
