Results indicated that partial least squares (PLS) models based on infrared spectra were proven suitable as practical analytical methods for predicting adulterant content in gasoline in the volume fraction range from 0% to 50%. The results obtained by PLS provided prediction errors lower than 2% (v/v) for all adulterant determined. Additionally, Soft Independent Modeling of Class Analogy (SIMCA) was performed using all spectral data (650–3700 cm 1) for sample classification into adulterant classes defined by training set and the results indicated that undoubted adulteration detection was possible but identification of the adulterant was subject to misclassification errors, specially for kerosene and turpentine adulterated samples, and must be carefully examined. Quality control and police laboratories for gasoline analysis should employ the proposed methods for rapid screening analysis for qualitative monitoring purposes.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2012-07-06T11:59:52Z No. of bitstreams: 1 CONFIG~1...-S0016236107002256-main-1.pdf: 1306283 bytes, checksum: 51f5f5ff5f460d5f9374ec05210b14b8 (MD5)Made available in DSpace on 2012-07-06T11:59:52Z (GMT).
