摘要:
以农业废弃物小麦秸秆为原材料,采用限氧热解炭化法制备了不同温度和含氧量条件下的生物炭,通过扫描电镜(SEM)和傅里叶红外光谱(FT-IR)测试研究其微观结构,酸碱滴定法测定生物炭表面的含氧官能团含量,并以盐酸四环素溶液为模拟废水,研究不同热解工艺条件(温度、含氧量)对生物炭吸附及活化过一硫酸盐(PMS)降解盐酸四环素性能的影响。结果表明:在热解温度500 ℃、高氧条件下制备的生物炭对盐酸四环素的去除性能最佳。热解工艺条件对生物炭表面含氧基团、吸附性能及活化PMS性能都有显著影响。研究结果为生物炭的制备及应用提供了有价值的探索与尝试。

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.
