Evaluating the Use of UV Absorbance for the Differentiation of Humified From Non-Humified Materials.

ABSTRACT:

Background

Products containing humic acids (HA) and fulvic acids (FA) have significant commercial potential; however, unknown to the consumer, some products may be mislabeled or contain adulterants. The prevalence of mislabeling and adulterants is found primarily in FA products. Using UV-Vis spectroscopy to differentiate between real and fake FA products is practical and desirable.

Objective

The objective of this study was to expand the dataset generated using a UV-Vis-based method proposed by Mayhew et al., 2023.

Methods

In total, 30 test samples were used to generate 90 test portions (three replicates per test sample) for analysis using the UV-Vis methodology outlined in Mayhew et al., 2023, which in this study is referred to as the UVAC (UV absorbance confirmation)
