热解工艺条件对生物炭活化过硫酸盐性能的影响
Influence of pyrolysis process on persulfate activation with biochar
摘要
Abstract
Using agricultural waste wheat straw as raw material,biochar was prepared by an oxygen-limited pyrolysis carbonization method under different temperature and oxygen content conditions.The microstructure of the biochar was studied through Scanning Electron Microscopy(SEM)and Fourier Transform Infrared Spectroscopy(FT-IR),while acid-base titration was used to determine the oxygen functional group content on the surface of the biochar.Tetracycline hydrochlorde acid solution was used as a simulated wastewater to investigate the effects of different pyrolysis conditions(temperature,oxygen content)on the adsorption and persulfate(PMS)activation performance of biochar in degrading tetracycline hydrochloride.Results showed that biochar prepared under pyrolysis temperature of 500℃and high oxygen conditions exhibited the best removal performance for tetracycline hydrochloride.The pyrolysis process conditions have significant effects on the oxygen-containing groups on the surface of the biochar,as well as its adsorption and PMS activation performance.The research findings offer a reference to the preparation and utilization of biochar.关键词
