“…13 The latter problem is seldom discussed in the scientific literature, although Furtmann 14 and Sjödin 15 have considered these polar surface attraction phenomena in investigations of phthalates and organohalogens, respectively. Liquid-liquid extraction using an organic solvent is the most commonly applied method for analysis of TBBPA in sediments or wastewater, 16,17 and solid phase extraction (SPE) has been employed to determine TBBPA in human plasma 9,18 and serum. 19 Although much analytical and environmental data on TBBPA have been accumulated and a paper concerning analysis of the derivative TBBPA bis(2,3-dibromopropylether) has been published 5 , little has been reported about the ether derivatives in the TBBPA family.…”

To cite this version:Susanne Jonsson, Maritha Hörsing. Investigation of sorption phenomena by solid phase extraction and liquid chromatography for the determination of some ether derivatives of tetrabromobisphenol A. Journal of Physical Organic Chemistry, Wiley, 2009, 22 (11) AbstractObserved sorption and chromatographic behaviour served as a starting point for examination of four ether derivatives of the flame retardant tetrabromobisphenol (TBBPA); dihydroxyethyl (DHEE), dimethyl (DMe), diallyl (DAE) and dibromopropyl (DBPE). To date, there is little or no information about these compounds in the scientific literature. The targets in the present study had calculated log K ow values of 6.0-10. A broad range of different types of solvents were used in order to elucidate the mechanisms of sorption onto silica (glass) and two solid phase extraction cartridges based on polystyrene divinylbenzene polymers, hydroxylated (Isolute ENV+) and vinylpyrrolidone (Oasis HLB) containing units. Also, three chromatographic columns (C18, C8, and dual C18-based, i.e. a polar ligand together with C18 on a silica surface) were evaluated. The following were observed: desorption of the targets from silica surface by 1-propanol showed the best results and the yields were further improved by silylation of the surface. Regardless of the experimental test conditions applied, the lowest recovery was seen for the DMe derivative, followed by TBBPA itself, which had calculated log K ow values in between the other targets. A washing solution containing up to 70% of methanol could be used without elution of the targets from the . The dihydroxethyl ether derivative of TBBPA is most probably not affected by environmental relevant pH due to a likely high pKa (ca 15). Also, this study shows that the polar character of the dual-phase column was not as pronounced as asserted by the manufacturer.

“…Currently, available extraction techniques for aqueous samples (e.g., tap water, surface water and wastewater) include Liquid-liquid extraction (LLE) (Zafra et al, 2003), solid phase extraction (SPE) (Zaharie, 2006;Gómez et al, 2007;Gros et al, 2009) and solid phase microextraction (SPME) (Pablo Lamas et al, 2004) …”

“…While large volume injection has been reported to decrease the method detection limits (MDLs) of GC analysis the introduction of co-extractants and residues from the derivatizing agents do compromise the column integrity so its use is not widespread. Typical temperature program is from 50 °C to 300 °C with a run time of 30 -45 mins (Boyd et al, 2003;Zafra et al, 2003;Weigel et al, 2004;Gibson et al, 2007;Gómez et al, 2007).…”

“…Quantification analysis is usually achieved by compounds molecular ions and fragment ions in selective ion monitoring (SIM). Selective ion monitoring improves sensitivity of target compounds by only acquiring data of target compounds with no attempt to acquire data of non-target compounds (Boyd et al, 2003;Zafra et al, 2003;Weigel et al, 2004;Lishman et al, 2006;Gibson et al, 2007).…”

All rights reserved.iv DEDICATION It is not easy to start pursuing a Ph.D and it becomes even harder towards the end. It is a kind of job that makes me start to question myself; it is a period of time in my life that I am desperate to call for help. But I am indeed blessed.I dedicate this dissertation to my parents, without their understanding and support and most of all love, it is impossible for me to walk so far on my way of pursuing my dream. They not only gave me life but also taught me how to become a better person.I dedicate this dissertation to my husband, without him, I will never know the colorful and beautiful part of life. He lets me feel peaceful and powerful when I face difficulties. An ASE-SPE-GC-MS method was developed and applied to the analysis of the sediment and soil area where reclaimed water was used for irrigation. Most analytes were below detection limits, even though some of analytes were detected in the reclaimed water at relatively high concentrations corroborating the fact that PPCPs do not significantly partition to mineral phases.
