Activated carbon adsorption is known as an efficient treatment process for water contaminated with pesticides. The adsorbability of pesticides onto activated carbon after their degradation was investigated. The degradation ratio and adsorption equilibrium were examined in batch experiments on fenitrothion and diazinon as pesticides. These concentrations and also adsorbability fell down after degradation processes including ultraviolet radiation, ozonation, hydrolysis and aerobic biodegradation. The extent of change in activated carbon adsorbability varied with the degradation processes. Degradation was found to have critical effects on adsorbability and to be important to achieve good efficiency in the water treatment system.
