| Abstract: | The photocatalytic degradation of low-acidic ruby N-5BL is studied by the orthogonal design under sunlight in Fe3O4/citrate/H2O2 system. The experiment result indicates that the decolorization reaches 95% under 0.04 g/L low-acidic ruby N-5BL,pH=2,1.0 g/L Fe3O4,1.5 g/L sodium citrate, reaction 30 min and volume fraction of H2O2 is 0.5% ,the azo group -N=N- and aromatic structure of the N-5BL are decomposed. |
