摘　　要：分别采用Fenton法和微波法对吸附活性艳红的活性炭进行再生,研究了H_2O_2加入量、n(H_2O_2)︰n(Fe^(2+))、pH、反应时间、温度、微波功率以及微波辐照时间对再生效果的影响。实验结果表明:在n(H_2O_2)︰n(Fe^(2+))=40︰1,H_2O_2加入量为2mL,pH为4,反应时间为60min时,Fenton再生效率达78.16%;在微波功率为700 W,微波辐照时间为2min时,微波再生效率达56.10%。原炭、Fenton再生炭和微波再生炭的吸附等温线符合Langmuir吸附等温模型。The experiment was performed for the regeneration of reactive brilliant red X-3B exhausted activated carbon by Fenton reagent and microwave.The factors of H 2O 2 dosage,molar ratio of H 2O 2 to Fe 2+,pH,time,temperature,microwave power and irradiation time were studied.The experiment results showed that,when H 2O 2 dosage was 2 mL,the molar ratio of H 2O 2 to Fe 2+was 40,the pH was 4,the time was 60 min,the temperature was 40℃,the regeneration rate was 78.16%.When microwave power and irradiation time were 700 W and 2 min respectively,the regeneration rate was 56.10%.The adsorption isotherms of X-3B on virgin,Fenton regeneration and microwave regeneration of activated carbon respectively were all in accord with Langmuir equation.
