风化煤中黄腐酸的提取及其表征研究进展

Research Progress on Extraction and Characterization of Fulvic Acid from Weathered Coal

黄腐酸类物质在工业、农业、林业和医药等领域有广泛的应用,风化煤中存在丰富的黄腐酸,从风化煤中提取黄腐酸是风化煤非燃料利用,提高其附加值的重要途径。现有的黄腐酸提取工艺过程中,技术难度大,产量少,因此黄腐酸的研究受到国内外学者的关注。本文主要介绍了黄腐酸的提取和表征方法,对各种提取方法优缺点进行了评价,对黄腐酸的表征方法进行了分析。

Fulvic acid is widely used in industry, agriculture, forestry and medicine and other fields, there are abundant of fulvic acid in weathered coal, extraction of fulvic acid from weathered coal is a way of non fuel utilization for improving the added value of weathered coal. In the process of extracting fulvic acid, the technology is difficult and the yield is low. Therefore, the study of fulvic acid has attracted the attention of scholars at home and abroad. The extraction and characterization methods of fulvic acid were introduced. The advantages and disadvantages of various extraction methods were evaluated, and the characterization methods of fulvic acid were analyzed.
