摘要：

Adsorption performance of activated carbon for nitro phenol isomers was investigated. The results showed that the highest adsorption capacity of o-nitrophenol, m-nitrophenol, p-nitrophenol on activated carbon are 676.03, 475.17 and 449.56 mg/g under the temperature of 25°C and neutral conditions, respectively. The adsorption behavior of o-nitrophenol on activated carbon is different from the other two isomers. With the increasing of temperature, adsorption of o-nitrophenol in activated carbon was also increased. Under the acidic conditions, the adsorption amount of nitro phenol isomers was in the order of o-nitrophenol>p-nitrophenol>m-nitrophenol. Adsorption of m-nitrophenol can be improved in activated carbon by increasing the pH value. The adsorption isotherms of nitro phenol strictly accord with Langmuir equation, which is a single molecule layer absorption.
