Abstract

ZnO nanopowders were prepared by solutioncombustion method SCM The SCM ZnO nanopowders were treated by five different dispersants They were used as photocatalysts to remove Ag+ ions from used photographic developing solutions The Ag+ ion removal rates by the dispersed SCM ZnO nanopowders were then compared with those by other photocatalyst powders such as commercial ZnOJunsei Japan P25 TiO2 Degussa Germany and TiO2 powder prepared by homogeneous precipitation process at low temperature HPPLT The dispersion of SCM ZnO nanopowders in the solution enhanced the Ag+ ion removal rate up to about 13 folds compared with P25 TiO2 nanopowders and 2 folds to SCM ZnO nanopowders without dispersion Sodium hexametaphosphate was the most effective dispersant among them
