Abstract：

Polyacrylic　acid,　Chitosan　and　nanosilica　particles　composite　(PCNS)　was　prepared　for　enrichment　of　U　(VI)　from　aqueous　solutions.　Adsorption　tests　controlled　by　different　parameters　including　contact　time,　pH,　initial　concentration　of　UO2　2+　and　coexistence　ions　were　examined.　FTIR,　SEM　and　EDX　studies　proved　the　formation　of　composite　and　confirmed　efficient　adsorption　of　UO2　2+　by　PCNS.　The　experimental　datas　fit　the　Langmuir　and　pseudo-second-order　models,　the　RL　(0.115–0.645)　indicates　the　adsorption　of　UO2　2+　onto　PCNS　are　favorable.　The　value　of　qm　(451.118 mg g−1)　and　adsorption–desorption　experiments　showed　PCNS　hydrogel　can　be　reckoned　as　a　high　efficienct　and　sustainable　material　for　removal　of　U　(VI).　©　2018,　Akadémiai　Kiadó,　Budapest,　Hungary.
