Derived organic compounds, resulting from fractional distillation of crude oil often end up in wastewater and surface water causing irreversible effects on aquatic ecosystems. Thus, it\u2019s necessary to identify and qualitatively determine the total content of petroleum products in water, by classical chemical, chromatographic and infrared spectroscopy methods. Gathering high-resolution spectral data was performed by a modern method, Fourier transform infrared spectrometry (FTIR), a relatively precise, high accuracy data method. The study\u2019s main purpose is to describe most important steps to be followed to obtain representative results for the use of FTIR spectrometry in determining total content of petroleum products in water. Steps described in the study involve drawing the baseline, calibrating the method with certified reference materials and estimating the uncertainty degree of the analysis method used. The study of total content of petroleum products is addressed especially to researchers in the field of analytical chemistry to update the methods used, environmental engineers to estimate the pollution degree of a body of water and (PhD) students who want to deepen the field of petroleum compounds analysis.<\/jats:p>","DOI":"10.1051\/matecconf\/202237300063","type":"journal-article","created":{"date-parts":[[2022,12,20]],"date-time":"2022-12-20T09:25:39Z","timestamp":1671528339000},"page":"00063","source":"Crossref","is-referenced-by-count":4,"title":["Analysis of total content of petroleum products in water by using FTIR spectroscopy"],"prefix":"10.1051","volume":"373","author":[{"given":"Alexandru Florin","family":"Simion","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Angelica Nicoleta","family":"G\u0103man","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vlad Alexandru","family":"L\u0103utaru","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"250","published-online":{"date-parts":[[2022,12,20]]},"reference":[{"key":"R1","unstructured":"Standard RO 7877\u20132 (1995)"},{"key":"R2","doi-asserted-by":"crossref","first-page":"165","DOI":"10.1289\/ehp.8982165","volume":"82","author":"Wallace","year":"1989","journal-title":"Environmental Health Perspect"},{"key":"R3","doi-asserted-by":"crossref","first-page":"215","DOI":"10.1111\/j.1745-6584.1994.tb00636.x","volume":"32","author":"Davis","year":"1994","journal-title":"Ground Water"},{"key":"R4","unstructured":"IRtracer100 User System Guide Instruction manual Shimadzu Fourier Transform Infrared spectrophotometer.
