Method for determining raw materials of humic acid product by adopting fluorescence method and method for quickly detecting content of humic acid in humic acid product

Abstract

The invention relates to a method for measuring raw materials of a humic acid product by adopting a fluorescence method and a method for quickly detecting the concentration of humic acid after the raw materials of the product are determined. Specifically, by the use of the characteristic of a fluorescence peak of the humic acid prepared from different types of raw materials, the raw materials of the product are judged by measuring an emission wavelength and an excitation wavelength; after the concentration of a sample is measured by adopting a one-step volumetric method, a linear equation of the concentration of the humic acid and the fluorescence intensity is obtained by measuring a linear relation between the concentration of the humic acid and the fluorescence intensity within a certain concentration range; then the content of the humic acid in the product can be calculated according to the linear relation only by measuring the fluorescence intensity of the solution of the humic acid product prepared from the raw materials.
