Extraction and determination of iodide by hollow fiber based liquid liquid liquid microextraction followed by flow injection photochemical reaction and UV Vis detection Maryam Shahrajabian m shahrajabian@ch iut ac ir september 2013 Department of Chemistry Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Lanquage Farsi Supervior Assoc Prof Mohammad Saraji saraji@cc iut ac ir Abstract In this thesis hollow fiber based liquid liquid liquid microextraction HF LLLME followed by flow injection and spectrophotometric detection was applied as a simple method for extraction and determination of iodide in milk and river water For determination of iodate in edible salt the iodate was converted to iodide The extraction of iodide was carried out using a cationic surfactant Aliquat 336 which dissolved in hexyl acetate as organic phase for filling the porous of the hollow fiber wall and 0 1 M ClO4 solution as acceptor phase in the lumen of the fiber Iodide was oxidized to iodine in a a photochemical reaction coil A mercury lamp was used as a UV source for the reaction The iodine showed a maximum absorption at 445 nm The factors affecting the HF LLLME and determination include type of organic solvent concentration of surfactant type of acceptor phase concentration of acceptor phase ionic strength volume of donor stirring rate and extraction time were optimized Tube length of reaction coil and carrier flow rate were also optimized Analytical parameters include intra and inter day relative standard deviation 4 5 11 linear dynamic range 5 1000 and enrichment factor 350 were calculated Key words Hollow fiber liquid phase microextraction flow injection cationic surfactant photochemical reaction spectrophotometric method PDF created with pdfFactory trial version www pdffactory com PDF created with pdfFactory trial version www pdffactory com
