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 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-1dithiocarbamate salt as ligand and polyethylene glycol tert-octylphenyl ether (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.
