Solvent-Resistant Polymeric Sensors for Adulteration Detection in Liquid Fuels
(AMER SCIENTIFIC PUBLISHERSVALENCIA, 2012)
Polymeric sensors with improved resistance to organic solvents were produced via the layer-by-layer thin film deposition followed by chemical cross-linking. According to UV-vis spectroscopy, the mass loss of polyaniline/poly(vinyl ...
Rapid and sensitive method for detecting adulterants in gasoline using ultra-fast gas chromatography and Partial Least Square Discriminant Analysis
(2018-03-01)
In the last years, the Brazilian Fuel Quality Monitoring Program drastically reduced the number of analyzed fuel samples as consequence of the current economic crisis in the country. The impoverishment of the monitoring ...
Screening analysis to detect adulterations in Brazilian gasoline samples using distillation curves
(elservir, 2004)
Data on evaporated fraction temperatures obtained from the distillation curves of Brazilian gasolines were employed to identify
adulterated samples by applying the Soft Independent Modeling of Class Analogy (SIMCA) model. ...
Álcool etílico combustível (AEC): Uma revisão da literatura
(Universidade Federal de São Paulo, 2023-07-05)
A produção de etanol combustível no Brasil tem grande representatividade no cenário mundial, uma vez que o país atingiu o segundo lugar com a produção de 48,6 milhões de m³, em 2021. A capacidade de processamento da ...
Multivariate calibration in Fourier transform infrared spectrometry as a tool to detect adulterations in Brazilian gasoline
(2008)
In the present work, Fourier transform infrared spectroscopy (FTIR) in association with multivariate chemometrics classification
techniques was employed to identify gasoline samples adulterated with diesel oil, kerosene, ...
