Zinc chromite (ZnCr2O4) was obtained by the thermolysis of new Zn(II)-Cr(III) oxalate coordination compound, namely [Cr2Zn(C2O4)4(OH2)6]·4H2O. The synthesized precursor was characterized by chemical analysis, vibrational spectrum and thermal analysis. The zinc chromite obtained after a heating treatment of the precursor at 450ºC/1h were investigated by various methods such as XRD, IR, TEM coupled with SAED measurements. The photocatalytic performance of nanosized zinc chromite was assessed for the degradation and mineralization of humic acid (HA) from drinking water source, envisaging the development of the advanced oxidation process for the drinking water treatment technology. A mineralization efficiency of 58.95% was achieved after 180 minutes of 50 mg L-1 HA photocatalysis using zinc chromite under UV irradiation, in comparison with the photolysis that did not allow HA mineralization. |
