The invention relates to a new application form of low molecular weight alkali metal huminates wherein the waterfree low molecular weight alkali metal huminate is bound to an inorganic, hydrogen bridge forming, carrier material such as titanium dioxide, aluminum oxide, highly dispersed silicium dioxide, or clay.

Waterfree application form of low molecular weight alkali huminates

The invention relates to a synthetic preparation of alkali metal salts of low molecular weight humic acids wherein multi-valent phenols are oxidized in a weakly alkaline aqueous medium at a temperature in the range of 15.degree. to 40.degree. C. Subsequently, the reaction mixture is adjusted to a pH value ranging between 6.2 and 7.2 and/or buffered. The low molecular alkali metal huminate is then purified through purification means including preparatory chromotography, ultra-filtration, ultra-centrifugation, or electrodialysis and separated from undesirable by-products.

Method for the preparation of low molecular weight alkali metal huminates

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.
