Abstract:
The soybean straw was used as raw material to prepare the biochar adsorbent at 400, 500 and 600℃,which were named BC400,BC500 and BC600. Phenol was subject to batch adsorption in aqueous medium by the prepared soybean straw biochar. The results of adsorption experiments showed that the preparation temperature of biochar significantly affected its adsorption effect on phenol. The adsorption capacity of phenol from three kinds of biochar was BC500> BC600> BC400. In addition,the initial concentration of phenol in waste water, the temperature and time of adsorption could also affect the adsorption effect. When the initial concentration of phenol was 40 mg·L-1 and the adsorption temperature was 45℃,the removal rate of phenol was up to 86% treated by BC500. The isothermal adsorption line for phenol conforms to the Langmuir mode and the Freundlich mode. The results showed the best condition of phenol removal from aquous solution by soybean straw biochar, thus providing a theoretical basis for the removal of organic pollutants such as phenol.
