摘要：

The adsorption of 2,4-dinitrophenol and 2.6-dinitrophenol on non-polar and polar adsorbents was studied. The results showed that the equilibrium adsorption did not comply with the Langmuir equation and was not mono-layer absorption. It is of interest to notice that the effect of pH on the adsorption of 2.4-or 2,6-dinitrophenol onto ADS-7 and ADS-21 was very small. The result is explained by hydrogen bonding interaction between 2, 4- or 2. 6-dinitrophenol and the adsorbent ADS21. The large adsorption capacity of dinitrophenol onto ADS-21, which was about 500 mg/g at an equilibrium concentration of 400 mg/L. and the small dinitrophenol leakage in the effluent from ADS- 21 column presented a good prospect for treatment of wastewater containing dinitrophenol with absorbent ADS-21.
