摘 要:现行标准GB11957-1989对腐植酸复肥中腐植酸测定方法操作步骤繁,手续多,耗时长。本文以容量法测定腐植酸复肥中腐植酸。总体方差0.087%,实验方法与标准方法不存在显著性差异;本方法操作手续简便,具有较好的准确度和精密度。结果满意。Current standard method GB11957 - 1989 for determination of the content of humic acid in compound fertilizer of humic acid needs multisteps and is time consuming. In this paper, content of humic acid in compound fertilizer of humic acid is measured by volumetric method. The empirical likelihood is 0. 087%. No great difference exisited between the results obtained by our method and that obtained by the standard method. Methods reported here is simple, precise and accurate with satisfied result.
