Abstract:
One of the latest atomic spectroscopic techniques for measurement of trace elements in biodiesel and crude oils is Microwave Plasma Atomic Emission Spectrometry (MP-AES). This technique can replace other atomic spectrometric techniques such as atomic absorption spectrometry (AAS), graphite furnace atomic absorption spectrometry (GF-AAS), and compliment inductively coupled plasma atomic emission spectrometry (ICP-AES) and inductively coupled plasma mass spectrometry (ICP-MS), which are widely used in the petroleum industry. Performing elemental analysis in locations where obtaining argon is a challenge for the petroleum industry. MP-AES technology is a suitable alternative for this industry. Although other atomic spectroscopic techniques mentioned above are used in the petroleum industry, ASTM D02.03 Committee on Elemental Analysis is currently working towards development of two standards. There is an immediate need to define and implement an ASTM standard that would describe a procedure for the determination of trace elements in petroleum products using MP-AES. This work will present the proposed method which describes, the multi-element determination of trace elements by MP-AES in biodiesel and crude oil. In this case, we used Premisolv or o-xylene to dilute the samples and standards and then added an internal standard of Scandium and Yttrium into each diluted sample.
