Microwave Digestion of Crude Oils and Oil Products for the Determination of Trace Metals and Sulphur by Inductively-Coupled Plasma Atomic Emission Spectroscopy

摘要

A study on the oil microwave digestion for determination of trace metals and sulphur in oil samples by ICP-AES was conducted by examination of the kinetic relationship of microwave digestion processes with different crude oil types, the mechanism of C6 hydrocarbon digestion reactions, and the recoveries of metals and sulphur during microwave digestion. The oil microwave digestion and ICP-AES measurement techniques developed in this study have been applied to more than 110 different oil samples for determination of 19 elements including Ni, V, Ti, Pb, Mn, Ba, Zn, Sr, Se, and S.
