Abstract

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%).

喀尔加斯湖泥球的化学成分

采用x射线、ICP-OES、GS/MS等化学和仪器方法对新疆省喀尔加斯湖的球状体进行化学和有机质组成测定。结果表明，喀尔加斯湖的似球体属于硫化氢泥。微量元素含量在0.5 ~ 480ppm之间。总有机质(TOM)中腐殖质占18.08%，脂质占6.56%，碳水化合物占15.95%。此外，非极性溶剂和极性溶剂提取的有机质占总有机质的1.83%。采用气相色谱-质谱联用技术(GC/MS)对有机提取物进行分析，鉴定出110种有机化合物。主要化合物有烃类及其衍生物(16.27%)、羧酸(12.94%)、邻苯二甲酸二烷基酯(6.52%)、元素硫(4.53%)、醇(17.65%)、含卤烃(2.26%)、含氮化合物(12.19%)、环烃(0.41%)、甾体(0.49%)和酮(14.52%)。
