Abstract
Abstract
Mechanochemical method is an efficient processing method that uses mechanical means to change the structure and physical and chemical properties of objects. This article takes peat from Erlintu Town, Yuyang District, Yulin City, Shaanxi Province as an example. It is activated by mechanochemical method, and then humic acid and fulvic acid are extracted by alkali-soluble acid purification technology. The results show that mechanochemical the method can improve the extraction rate of humic acid and fulvic acid in peat. Among them, the mechanochemical method with percarbonamide as the oxidant and sodium hexametaphosphate as the grinding aid has the best effect of activating peat. Mechanochemical methods can increase the molecular condensation degree and molecular relative mass of humic acid, but reduce the molecular condensation degree and molecular relative mass of fulvic acid.
