摘　　要：为了解决制药行业土霉素菌渣处置的难题,该文以土霉素菌渣为原材料,K2CO3为活化剂,采用化学活化法制备土霉素菌渣活性炭。通过电镜扫描和氮气吸附对较佳条件下制备的活性炭特性进行了表征。实验得出制备土霉素菌渣活性炭的较佳工艺条件为:活化温度800℃,活化时间3 h,活化比1∶3。该活性炭的苯酚吸附值为215 mg/g,比表面积达1 593.09 m2/g,亚甲基蓝吸附值为117 mg/g。该活性炭孔结构丰富,主要以微孔为主,平均孔径为1.09 nm,微孔孔容为0.54 cm3/g,中孔孔容为0.27 cm3/g。In order to solve the problem of oxytetracycline bacterial residue disposal of pharmaceutical industry, the activated carbons prepared from oxytetracycline bacterial residue with K2 CO3 under chemical activation are investigated here. The properties of the activated carbons under better conditions are performed by sanning electron microscopy and Nitrogen adsorption. Experimental results show that the better process conditions of preparation for oxytetracycline bacterial residue activated carbons are 800 ~C activation temperature,3 h activation time and 1：3 ac- tivation ratio. The phenol adsorption of these activated carbons is 215 mg/g,the special surface area is 1 593.09 m2/g and the methylene blue adsorption is 117 mg/g. The activated carbons are affluent in pores,which are mainly micropores. The average pore size of the activated carbons is 1.09 nm, and the micropore volume and mesopore volume are 0.54 cm3/g and 0.27 cm3/g respectively.
