| Abstract: | Methylene blue was degradated by photocatalytic reaction of Fe3+ /Fe2+ system using Nafion cation-exchange membrane embedded by Fe2+, with decolorization rate up to 90%. The influence of H2O2 and pH was discussed. The photocatalytic degradation of methylene blue solution meets the first-order kinetic law, and the apparent rate constant was 0.5689min-1. |
