ABSTRACT:
Alkali metal or ammonium salts of humic acids, referred to as alkali metal huminates of low molecular weight, obtained by slurrying humic-containing matter in alkaline or ammoniacal aqueous solutions, separating the resulting suspension from coarse solid matter and, through centrifugation, freeing the solution from extremely fine solid materials and high molecular weight huminates. The resulting solution is neutralized and buffered at a pH value ranging from 6.2 to 7.2, and is again purified through centrifugation. From this solution, a low molecular weight fraction is separated. The resulting alkali metal huminates of low molecular weight are useful as therapeutic agents in wound healing and for use in highly effective synthetic mud baths.
