The single component ad-sorption of an acidic dye, Acid Yellow 117, and a basic dye, Methylene Blue, onto several adsoroents-bamooo, waste wood, bamboo char, waste wood char, bamboo activated carbon, wood activated carbon and active carbon F400 were conducted. Based on a Langmuir analysis, the monolayer adsorption capacities were determined. Three of the adsorbents were selected for binary layer adsorption to check the multilayer concept and the potential application for better adsorbent usage. The two cheapest adsorbents, bamboo and wood are compared with the commer-cial activated carbon F400, and all three systems were successful.展开更多
