| Abstract: | The cotton pulp black liquor was catalyzed and oxidated with H2O2,TiO2 microparticles and TiO2 immobilized on support materials. The results indicated that TiO2 immobilized on active carbon had a more efficient catalytic ability than other type catalysts, and the removal efficiencies of chroma and COD reached 99.5％ and 73.7％ respectively under the condition that pH＝4.3, T ＝60 ℃ and t ＝100 min while 10 g catalyst and 0.04 L H2O2 were added into 1 L wastewater. |
