METHOD FOR SEPARATING AND ENRICHING FULVIC ACID IN SOIL THROUGH ACTIVATED CARBON

摘要

The invention discloses a method for separating and enriching fulvic acid in soil through activated carbon. The method comprises the steps of processing soil samples, extracting soil fulvic acid through acid liquor, extracting soil fulvic acid through weak base, extracting soil fulvic acid through strong base, enriching and purifying the fulvic acid for the first time, enriching and purifying the fulvic acid for the second time and the like. In this way, the fulvic acid in soil can be effectively enriched and separated, the activated carbon used as the enriching materials can be repeatedly utilized, the good method is provided for soil control and the like, and the material basis is provided for researching the fulvic acid in the existing technology by enriching and separating the fulvic acid.
