R.Silva, Márcia M.2012-04-11T18:31:38Z20100039-9140http://www.repositorio.ufba.br/ri/handle/ri/5592v. 83, n. 2Acesso restrito: Texto completo. p. 637-643.Lubricating oils are used to decrease wear and friction of movable parts of engines and turbines, being in that way essential for the performance and the increase of that equipment lifespan. The presence of some metals shows the addition of specific additives such as detergents, dispersals and antioxidants that improve the performance of these lubricants. In this work, a method for determination of calcium,magnesium and zinc in lubricating oil by flame atomic absorption spectrometry (F AAS) was developed.The samples were diluted with a small quantity of aviation kerosene (AVK), n-propanol and water to form a three-component solution before its introduction in the F AAS. Aqueous inorganic standards diluted in the same way have been used for calibration. To assess the accuracy of the new method, it was compared with ABNT NBR 14066 standard method, which consists in diluting the sample with AVK and in quantification by F AAS. Two other validating methods have also been used: the acid digestion and the certified reference material NIST (SRM 1084a). The proposed method provides the following advantages in relation to the standard method: significant reduction of the use of AVK, higher stability of the analytes in the medium and application of aqueous inorganic standards for calibration. The limits of detection for calcium, magnesium and zinc were 1.3 gg−1, 0.052 gg−1 and 0.41 gg−1, respectively. Concentrations of calcium, magnesium and zinc in six different samples obtained by the developed method did not differ significantly from the results obtained by the reference methods at the 95% confidence level (Student’s t-test and ANOVA). Therefore, the proposed method becomes an efficient alternative for determination of metals in lubricating oil.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2012-04-11T18:31:38Z No. of bitstreams: 1 __ac.els-cdn.com_S003991...38f6644216db96e39917dbd8329b4.pdf: 251257 bytes, checksum: 2bdba50ade1fbbe9b037a67ca1f362a7 (MD5)Made available in DSpace on 2012-04-11T18:31:38Z (GMT).
