摘要
微波反应具有加热速率快、选择性加热、加热均匀等优势,已成功用于制备微波生物炭。主要分析了原料组成、湿度、粒径、热解温度及时间、微波功率、微波吸收剂等因素对微波生物炭产量和质量的影响。在此基础上,综述了微波生物炭在环境修复领域的应用研究进展,结果表明微波生物炭是水中重金属离子、染料的优良吸附剂,对改善土壤理化性质、促进植物生长等方面可起到重要作用。最后分析了目前研究中存在的不足及未来的发展方向。
Microwave biochar has been successfully prepared based on the microwave reaction due to its advantages of fast heating rate,selective heating,uniform heating,etc.The effects of raw material composition,moisture,particle size,pyrolysis temperature,pyrolysis time,microwave power,microwave absorbent and other factors on the yield and quality of microwave biochar were mainly discussed.On this basis,the application of microwave biochar in environmental remediation was reviewed.The results showed that the microwave biochar was an excellent adsorbent for heavy metals and dyes,and also played an important role in improving soil properties and promoting plant growth.Finally,the shortcomings of the current research and the future development direction are analyzed.
