【 摘 要 】

The biochar adsorbent was prepared at 300, 400 and 500°C using the Seabuckthorn seed as raw material to remove the ethyl paraben in waste water. The results of adsorption experiments show that the initial concentration of ethyl paraben in wastewater, the preparation temperature of biochar, the temperature of adsorption can affect the adsorption effect of biochar on ethyl paraben. The adsorption capacity of three kinds of biochar to ethyl paraben was BC400> BC500> BC300. The isothermal adsorption line for ethyl paraben conforms to the Langmuir mode and the Freundlich mode.
