Uncatalyzed and catalyzed nanoscale Fe 0 systems were employed for the denitrification of unbuffered 40mgNL −1 nitrate solutions at initial neutral pH. Compared to microscale Fe 0 (<100mesh), the efficiency and rate of nitrate removal using uncatalyzed and catalyzed nano-Fe 0 were highly promoted, in which the maximum promoted rate was obtained using copper-catalyzed...
Nanoscale zerovalent copper supported on a cation resin was successfully synthesized to enhance the removal of carbon tetrachloride (CCl 4 ) from contaminated water. The use of the cation resin as a support prevents the reduction of surface area due to agglomeration of nanoscale zerovalent copper particles. Moreover, the cation resin recycles the copper ions resulting from the reaction between...
