ABSTRACT
In this study, Lead (Pb), Copper (Cu), and Tin (Sn) elements determined in corn samples were analyzed from three different regions of Sakarya province. A cloud point extraction (CPE) method was used for the metal determination study and analysis by inductively coupled plasma-optical emission spectroscopy (ICP-OES). In this study, optimization processes were performed in cloud point extraction 2-(4-sulphonylamidebenzo)hydrazide-1-dithiocarbamate salt as ligand and Triton X-114 as surfactant. Three different corn samples, soil samples, and certified reference materials (GBW10011 and GBW10012) were analyzed. Recovery values in corn samples were 95.5-97.1% for Cu, 101.8-105.2% for Pb, and 94.1-97.3% for Sn; Recovery values for soil samples were 99.3-104.3% for Cu, 93.6-103.3% for Pb and 99.5-101.6% for Sn detected among them.
