Abstract

In order to reduce environmental loading such as water pollution, a possibility is raised to substitute charcoal for detergent. Therefore, we study the efficiency of charcoal washing by examining detergency and performing component analysis of water that charcoal had been immersed. Effectiveness of added salt was also examined. In this report we showed that 1) detergency of charcoal was an order of synthetic detergent, compound detergent, charcoal, but was significantly higher than water; 2) the water immersed with charcoal was alkaline, and contained cation based on surface activity and phosphoric acid; 3) NaCl added into water dispersed the soil particle following Schulze-Hardy's law and resulted in the effective adsorption by charcoal. These results indicate that soil redeposition is lowed by charcoal washing.
