Nanosized zirconium dioxide particles as an efficient sorbent for lead removal in waters

摘要

Herein a new crystalline zirconium oxide was prepared by the sol-gel precipitation and calcination methods. TEM analysis proved that the prepared ZrO_2 particles are nanosized particles with average size of 10-20nm and XRD further illustrated its crystal pattern in nature. The competition tests also demonstrated its excellent selectivity towards lead ions by comparing D001 resin. Moreover, the resultant ZrO_2 particles could be regenerated and reused at least 3 cycles.
