Özet:

 

Results of experimental studies determining the increase of the  humic acids soluble in alkaline medium and represented by the carboxyl  groups (COOH) during the oxidation of an Elbistan lignite sample are  reported in this study.  The oxidation reaction was conducted in an  open circuit system in an oven and in atmospheric conditions at  temperatures between 90 and 150oC. The increase in oxygen  concentration provided by the air in the sample was allowed to proceed  from 36 to 144 hours.  Percent recoveries of humic acids soluble in  ammonium hydroxide for the oxidized samples were increased.  The humic  acid (ammonium humate) percent recovery reached 85.00% by  heating at 90oC for the period of 144 hours.
