This study was carried out to estimate the possibility on the removal of phenols and anilines, which were contained in pulp or dye waste water, and the reusability of plant materials, shepherd's purse and turnip. Most of phenols catalyzed with shepherd's purse were removed more than 90% in the presence of $H_2O_2$, and the removal was ranged from 53.1% for 2,6-DMP to more than 99% for 2,4,6-TCP when turnip was used as catalysts. The removal of anilines catalyzed with shepherd's purse was ranged from 42.2% for 2-CA to 78.7% for 3,4-DCA in the presence of $H_2O_2$, and in case of turnip, from 31.5% for 2-CA to 90.0 % for 2,4-DCA. The reuse of plant materials was proved to be possible for not only the batch method but also the continuous method. No decreasing removal was observed during 30 cycles in waster water contaminated with 100ppm of 2,4-DCP. However, it was observed that the removal was decreased with increasing the number of cycles in higher concentration of 2,4-DCP(800ppm). Therefore, it could be suggested that the number of reusable cycles depends on the initial concentration of substrates.
