Abstract:
The role of the humic acid in the process of mineralization of sandstone-type uranium deposits is influ- enced by some factors like pH value, temperature and ionic strength. Because some structural units of humic acid and fulvic acid are similar to aromatic organic acid of small molecular weight, in order to study the influence of humic acid in the process of mineralization of sandstone-type uranium deposits, some uranium complexes is ob- tained the existing state of uranium in humic acid is testified by using aromatic organic acid to replace humic acid.
