Evaluation of lignite humic substances oxidation stability by DSC induction period measurement

conference paper

English

Induction period of several humic fractions were measured by DSC in oxygen atmosphere. The fractions were obtained from lignite-derived humic acids by controlled oxidation. results are discussed from the viewpoint of humic acids stability and genesis.
