Abstract:
Ispitana je mogućnost uklanjanja Mo(VI)pomoću makroporoznog kopolimera sa amino ligandom, PGME-deta. Kinetika adsorpcije oksianjona Mo(VI), ispitana u temperaturnom opsegu od 25-70 °C jako zavisi od difuzije kroz pore i da se najbolje opisuje kinetičkim modelom pseudo drugog reda. Maksimalni adsorpcioni kapacitet raste sa temperaturom i iznosi 585 mg g-1 na 70 °C. Termodinamički parametri ukazuju na spontanost i endotermnost adsorpcije Mo(VI) na PGME-deta, uz povećanje entropije sistema.
