Abstract

In this study, Arsenic, which is found in the structure of field medicines, was determined by ICP-OES.  For arsenic analysis, Turkey was elected four different commonly used pesticides. These pesticides were commercially named A, B, C, and D samples. These samples were solubilized using the appropriate procedure by microwave digestion method. For arsenic determination, 188.980 nm wavelength measurements were made.The determination of the known acid first with ICP-OES was measured at high sensitivity. Arsenic amounts were measured as approximately 0.46 to 0.81 µg/g as the 95% confidence level in the samples and the average of 5 measurements.The validation process of this method was done according to the reference article. The results of the experiment were made with the electrochemical method, differential pulse polarography (DPP), and the results were found to be in agreement.
