用有机溶剂提取泥炭黄腐酸的研究

用有机溶剂丙酮，从泥炭中提取黄腐酸，通过对液固比，抽提时间，丙酮的含水量和抽提液的ＰＨ值等方面进行的正交试验和对黄腐酸提取率的分析，确定了提取黄腐酸的最佳工艺条件，为工业化生产提供了依据。同时，为降低成本，对用乙醇作为提取剂的可行性作了探索试验。

Study on Extracting Fulvic Acid from Peatby Organic Solvents

In this. paper, the study on exacting fulvic acid from peat by organic solvents is carried out. The optimum processing conditions such as the rate of solid to liquid, extracting time, the water content of acetone and the pH of the extracting liquid are obtained by meaus of orthogonal tests and analysis on the extraction rate of fulvic acid. The result will provide basis for industrial production. Meanwhile, in order to reduce the cost, the experiment is done to counter the feasibility of using ethanol as the extracting solvent.
