dc.descriptionFOCUSED-MICROWAVE-ASSISTED DIGESTION OF ENCAPSULATED LUBRICATING OILS: GRADUAL SAMPLEADDITION TO PRE-HEATED ACID. The applicability of the recently proposed procedure based on gradual sample addition tomicrowave-assisted pre-heated concentrated acid is limited by the sample viscosity. In this work, lubricating oil samples with high viscositywere encapsulated and manually added to the microwave-assisted pre-heated concentrated digestion mixture. The procedure was appliedfor determination of Al, Ca, Cr, Cu, Fe, Mg, Ni, P, Pb, Si, Sn, Sr, V, W, and Zn in lubricating oil by inductively coupled plasma opticalemission spectrometry (ICP OES). Determined and certified values for Ca, Mg, P, and Zn in lubricating oil were in agreement at a 95% confidence level.
