生化黄腐酸定量分析方法研究

Study on the method for the analysis of biotechnolongy fulvic aicd content

通过硫酸铝絮凝生化黄腐酸,并以在絮凝物中扣除灰分的方法来确定黄腐酸含量,我们将其定义为“絮凝重量法”。该方法既排除了生化黄腐酸中非黄腐酸有机物的干扰,又避免了碳系数取值的不同而引起的系统误差。

The method named as 'coagulative weight method 'which was quantified FA content in BFA by coagulating of FA in BFA with aluminum sulfate and then measuring the weight differece. The present method could avoid from the interference of non - FA organic matter and the error induced by the different option to carbon amount, and was a good method for the quality determination of BFA product.
