摘要
生物炭是植物和动物的生物质通过热解/炭化合成的稳定的碳产物,作为一种历史悠久的废物衍生土壤改良剂,其因具有改善土壤肥力及环境的能力而受到广泛关注,能够去除或固定土壤、水和空气中的污染物,减缓气候变化。为了提高生产性能和去除效率,很多学者研究了不同的热解和改性方法。该文主要综述了生物炭、磁性生物炭的制备与应用研究进展,总结了常用的制备方法,为后续生物炭复合材料的研究和应用提供参考。
Biochar is a stable carbon product synthesized by pyrolysis/carbonization of plant and animal biomass.As a long-standing waste-derived soil amendment,it can improve soil fertility and improve the environment and has re⁃ceived widespread attention.It can remove or Fix pollutants in soil,water,and air and slow down climate change.To improve production performance and removal efficiency,many scholars have studied different pyrolysis and modifica⁃tion methods.This article mainly describes the preparation and application of biochar and magnetic biochar,summa⁃rizes the commonly used preparation methods,and provides a reference for the subsequent research and application of biochar composite materials.
