| 英文摘要 | Two commercial and eight soil humic acids were characterized to evaluate the use of commercial humic materials in soil and environmental studies. Significant differences between commercial and soil humic acids were observed in ash content, major and micro-element constituents, E4/E6 ratio, total acidity and C-13-NMR spectroscopy; but data from stability constant and IR-spectroscopy were almost identical. The commercial materials appeared to be significantly less aromatic and more aliphatic in nature as compared with representative soil humic acids. The above discrepancies were interpreted as indicating an origin of the respective commercial product other than soil. The two commercial humic acids investigated may not originate from the same source material as evidenced by clear-cut differences in the intensity of the C-13-NMR spectra in almost all chemical shift regions. Due to the observed structural, compositional and characteristic dissimilarities, both between soil and commercial humic acids and between different commercial ones, the commercial humic products are not recommended to be used as analogues of real soil humic acids in soil and environmental studies. |
