摘要
腐殖酸是一类成分复杂的天然有机物质,存在于土壤、煤炭、湖泊、河流及海洋中,传统方法生产腐殖酸主要是采用氨水直接氨化法、碳化氨水法和堆沤发酵法等,现采用碱化酸析法生产腐殖酸,研究其生产的主要设备、操作要点、技术参数及使用方法。结果表明:采用碱化酸析法生产腐殖酸,产品含量高,使用方便,且便于保存。
The humic acid is a kind of composition of complex natural organic matters,present in the soil,coal,lakes,rivers and oceans,the traditional methods of production of humic acid is mainly the direct amination using ammonia,ammonia carbonation method and the heap fermentation and so on,now using alkaline humic acid chromatography to produce humic acid and study the major equipment,operating point,technological parameters and usage.The results showed that using alkaline to produce humic acid,the product content was high,easy to use and easy to save.
