| Abstract: | The optimal parameters for AB-8 adsorbing camphotree leaves polyphenol were determined as: 25 ℃,pH 5.68,the best desorbing solvent was 60% ethanol.The adsorbing achieved balance in 4 hours,and the adsorbing rate was 94.4%.The desorbing rate was 80.28% in 2 hours.Under the optimal conditions,the recovery rate was 75.78%,and the purity of polyphenol was 63.56%.The pattern of AB-8 adsorbing camphotree leaves polyphenol fit Langmuir equation,and the saturated adsorption capacity of AB-8 was 47.619 mg·g-1. |
