  Simultaneous extraction of the morpholino dithiocarbamate (MDTC) chelates of Cr(III) and Cr(VI) ion from aqueous samples was accomplished by applying fabric phase sorptive extraction (FPSE) using a cellulose fabric modified with a sol-gel/polytetrahydrofuran composite. Following extraction, the chelates were separated by HPLC on a reverse phase C18 column with acetonitrile:water (65:35; v/v) as the mobile phase and UV detection at 320 nm. A single peak is found for the Cr(MDTC)3 but two peaks are caused by Cr(VI) due to the formation of the complexes Cr(MDTC)2(OMDTC) and Cr(MDTC)3 (where OMDTC stands for oxy-MDTC). The limits of detection for the Cr(III) and Cr(VI) complexes are 0.001 and 0.003 ng∙mL‾1, respectively. The method can be used for the determination of chromium species in aqueous samples and displays high pre.. View More»
