Abstract:
Retke zemlje se smatraju materijalima budućnosti zahvaljujući njihovim brojnim primenama u koje spadaju medicinska dijagnostika, nuklearna postrojenja, naftna industrija, itd. Višeslojne ugljenične nanotube, koje imaju jedinstvena fizizko-hemijska svojstva, u ovom radu su ispitane kao sorbenti lantanoida gadolinijuma iz vodenih rastvora. Zavisnost sorpcije Gd od pH ispitivana je u opsegu pH 3‒11 na sobnoj temperaturi (298 K). Ravnotežna sorpcija u opsegu početnih koncentracija 5‒50 mg L−1 analizirana je Langmirovim, Frojndlihovim i Redlih-Petersonovim modelima. Kinetika sorpcije analizirana je modelima pseudo-prvog reda, pseudo-drugog reda i frakcionog stepena.

Key words:
gadolinijum, višeslojne ugljenične nanotube, sorpcija
