Study on Adsorption Properties of Activated Carbon for Nonylphenol   Adviser:
Abstract: Activated carbon is widely used in the daily life due to its advantages. In this study, the reeds was utilized to prepare activated carbon using different activated methods and impregnation ratios. The specific surface area and pore size distributions of the activated carbon were analyzed. Then the activated carbon was used to adsorb the nonylphenol in the wastewater, and the adsorption kinetics was determined. Moreover, the impacts of the factors such as dosage, adsorption time and impregnation ratio on the adsorption efficiency were also investigated. The experimental results showed that activated carbon prepared by phosphoric acid had the smallest micropore and the best absorption capacity for nonylphenol. The optimal dosages of activated carbon prepared by phosphoric were 0.50g/L, and the optimal impregnation ratio was 1:2. After 90 minutes, the adsorption quantity of nonylphenol reached the maximum. Activated carbon prepared by potassium hydroxide had some micropores, but the surface area was smaller and the micropore was larger, and the absorption capacity for nonylphenol was normal. The optimal dosages of activated carbon prepared by potassium hydroxide were 1.00g/L, and the optimal impregnation ratio was 1:2.5. After 30 minutes, the adsorption quantity of nonylphenol reached the maximum. Activated carbon prepared by zinc chloride had many micropores, the value of surface area and  micropore were on the middle scale, and the absorption capacity for nonylphenol was better. The optimal dosages of activated carbon prepared by zinc chloride was 1.00g/L, and the optimal impregnation ratio was 1:2.5. After 60 minutes, the adsorption quantity of nonylphenol reached the maximum. The three adsorption processes of activated carbon to nonylphenol were best fitted with the pseudo-second-order kinetic mode.
