%X This article studied the preparation methods of the adsorbent by irrigating soil of beaches.From a series of orthogonal tests,the absorbing ability of the synthesized adsorbent to o-nitrotouene in water was investigated by adding several activators(ZnCl2,HCl,KOH and H3PO4) under various conditions such as the dosage of added straw,concentration of the activator,the time of acting and the temperature of the activator.The result showed that HCl was the best activation agent,and the optimum preparation conditions were addition of straw of 15%,HCl concentration of 2 mol/L,the ratio of solid to liquid of 1∶ 1,activation temperature of 400℃,time of activation of 1 hour.These conditions were under the protection of N2 gas and the absorption efficiency of the prepared soil adsorbent for the o-nitrotoluence in water was above 90%.
