Test Method Validation for Quantitative Determination of Heavy Metals in Olive Oils by Inductive Coupled Plasma (ICP – AES) using Low Cost and Simple Extraction Method

摘要: The aim of this study is to demonstrate a valid and simple extraction method for the heavy metals from olive oil its quantitative determination by ICP-AES technique. Fifteen samples are collected different manufacturing companies originates five countries. Fourteen quantitively detected in all including; Aluminum, Arsenic, Calcium, Cadmium, Cobalt, Chromium, Copper, Iron, Potassium, Magnesium, Manganese, Nickel, Lead Zinc. A has been proposed raw based on diluted 10% HNO3. Test validation procedures have carried out analytical trace investigated samples. elements found be concentration range 0.0001 8.39 mg.kg-1. As result test validation; linearity (R2) above 0.99, recovery ranged between (72.63% 124.62%), limit detection quantitation (0.006– 2.32 µg.kg-1) (0.022 – 7.68 respectively. relative standard deviation (RSDs) repeatability ruggedness lower than 2.2% selected elements, which confirms precision method. results validity accurate, precise, rugged, selective, specific stable metal analysis that
