Trace element analysis in corn by cloud point extraction

In this study, Lead (Pb), Copper (Cu) and Tin (Sn) elements determined in corn samples were analysed 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 using 2-(4-sulfamoylbenzoyl) hydrazine-1-carboditoicacid as ligand and Triton X-114 as surfactant. Three different corn samples, three different 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, 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.
