Abstract
Introduction. Pollution of lands and water bodies with petroleum products is one of the main environmental problems in the territory of JSC Ozenmunaigas. The purpose of this work is to conduct a physico-chemical analysis of oil-containing wastes, such as oil sludge, dirty soil and asphaltresin-paraffin deposits, using infrared (IR) spectroscopy and gas chromatography-mass spectrometry. Two methods were used to analyze the composition of the waste under study: infrared spectroscopy, which allows detecting the presence of various organic and inorganic components, and gas chromatographymass spectrometry, which provides more accurate information about the chemical composition of hydrocarbon fractions. The results of IR spectroscopy showed the presence of water, clay minerals and organic substances, as well as absorption bands characteristic of methyl and methylene groups, aromatic compounds and oxygen-containing functional groups, which indicates the interaction of hydrocarbons with atmospheric oxygen. The data obtained make it possible to judge the composition of oil-containing waste and its possible impact on the environment. The use of such research methods is important for the development of environmental protection measures, including effective ways to clean up contaminated areas and prevent further contamination of reservoirs and soil.
