Chemical Composition of Peloid from Lake Khyargas

The purpose of the study was to determine chemical and organic matter compositions of peloid from Lake Khyargas in Uvs province by chemical and instrumental methods, including X-ray, ICP–OES, and GS/MS. Based on our results, it was identified that the peloid from Lake Khyargas belongs to hydrogen sulfide mud. The content of microelements ranged from 0.5–480 ppm. The peloid contains humic substance 18.08%, lipid 6.56%, and carbohydrate 15.95% in total organic matter (TOM). In addition, organic matter extracted by non-polar and polar solvents counts for 1.83% of TOM. The organic extracts were analyzed by gas chromatography-mass spectrometry (GC/MS) and identified 110 organic compounds in peloid from Lake Khyargas. There were compounds hydrocarbons and their derivatives (16.27%), carboxylic acid (12.94%), dialkyl phthalate (6.52%), element sulfur (4.53%), alcohol (17.65%), halogen bearing hydrocarbons (2.26%), nitrogen-containing compound (12.19%), cyclic hydrocarbons (0.41%), steroids (0.49%), and ketone (14.52%).
