It was based on the preparation of an emulsion followed by breaking the emulsion by centrifugation. The aqueous phase was extracted and collected for determination the trace elements using inductive coupled plasma – optical emission spectroscopy. The chemical and physical variables influencing the extraction were optimized. The LODs obtained were ranged from 1.2 µg L-1 to 5.8 µg L-1. The RSDs ranged from 1.1% to 6.7%. EIEB was suitable for determination of the analytes at µg L-1 levels in lubricants samples collected from several markets in Kalar and Sulaimani Cities UR - https://jgu.garmian.edu.krd/article_65684.html L1 - https://jgu.garmian.edu.krd/article_65684_c6ced2c879b48ddb64b33dc27be55be9.pdf ER -
