摘要
论述了褐煤中提取腐殖酸产品的方法及原理。采用空气氧化预处理、硝酸氧化预处理、超声波预处理三种方法提高腐殖酸的提取率。讨论了不同抽提剂对腐殖酸的提取率的影响。
This paper describes the principles and methods of extracting humic acid product trom lignite. Three pretreatments including air oxidation pretreatment, nitric acid oxidation pretreatment, ultrasonic pretreatment are used to increase the rate of humic acid extraction. Different solvents affecting the rate of humic acid extraction are discussed.
