Preparation and elemental composition

Popis výsledku v původním jazyce

The preparation of alkali humates and humic acids from raw materials of Czech Republic (coal, oxyhumolite, lignite, and peat) was aimed. Chosen preparation methods can be implemented in low tonnage technologies and in industrial production. The aim was to get substances available for application in biotechnologies and in human and veterinary medicine. Suspensions prepared by alkali extraction, executed aerobic in the suspension with use of potassium hydroxide were purihed by sedimentation and centrifugation. Humic acids obtained from the refined potassium humate solutions by coagulation by sulfuric acid were separated on filter, rinsed and dried. Other substances were prepared from coal and lignite after their oxidation by nitric acid. Raw materials and substances prepared from them were compared on the basis of their chemical and physical properties. Basic characteristics ? the moisture, content of ash, organic part, fulvic acids, leachable humic substances, functional groups (total a
