摘　　要：研究了一种测定腐殖酸纯度的方法—酸碱滴定法,并对影响此方法的浸提剂种类、加热浸提时间和加热氧化时间进行了分析,并确定了纯度测定方法的最优操作条件。结果表明:通过该方法可以简便准确地测定出腐殖酸纯度。In this paper, acid-basetitration means as a new way to measure humic acid content is studied, it analyses the influencing factors of measure, including the kind of distillers, the time of heating distilling and thoxidation, and finds out the most appropriate conditions for mensurating the purity. Results show that this means can measures the purity of humic acid easily and accurately.
