“…Adsorption effects are more relevant at lower concentrations [22], and this is probably the main reason why polymer bottles are less suitable for the experimental conditions of this study. It is also worth mentioning that tap water has been used in this adsorption study which poses a more complex, realistic and challenging matrix than traditionally used deionized water [24,31]. TBT does not only adsorb to the container walls but also interacts with ions and DOC present in the tap water in contrast to almost ligand-free deionized water.…”

Certified water reference materials are currently not available for most of the hydrophobic organic pollutants listed in the EU Water Framework Directive. To find the most suitable container type for subsequent reference material productions, feasibility studies for the preparation of waters with polycyclic aromatic hydrocarbons (PAHs), polybrominated diphenyl ethers (PBDEs) and tributyltin (TBT) close to environmental quality standards in water have been performed. Due to the hydrophobic nature of these compounds and their tendency to adsorb onto container walls, an adequate selection of the most appropriate material for containment, storage and transport of water reference materials is crucial. Three different materials (aluminium, amber glass and fluorinated polyethylene, FPE) and three volumes (500/600 mL, 1000/1200 mL and 2000/3000 mL, depending on commercial availability) were tested at ng L -1 level of the target compounds. FPE shows by far the highest loss of analytes due to adsorption onto the container walls for all compounds studied. Aluminium and glass are equally suited for PAHs and PBDEs, but aluminium is unsuitable as container material for TBT due to acid cleaning requirements. The volume of the containers had no dramatic effect on the adsorption behaviour of target compounds for the different volumes tested.

“…Other compounds with more ionic character may be solvent extracted as chelate complexes formed with diethyldithiocarbamate or tropolone. [218][219][220][221][222][223] Derivatisation to non-polar compounds followed by solvent extraction has been performed using hydride generation, 224,225 and ethylation with NaBEt 4 , 226,227 NaBPr 4 , 11,228 or NaPh 4 . 227,229 These methods are mainly used for organotin and organolead species, as well as for methylmercury.…”

“…Dialkyllead species were prepared daily as described previously [3]. The ionic organotin compounds were obtained from Ciba (Lampertheim, Germany) [5]. The Grignard reagents (c RMgX = 2 mol/L Et 2 O; R = Pr, Pe; X = Cl, Br) were provided by Aldrich (Milwaukee, USA).…”

“…Extraction of the organotin and organolead compounds from water samples can be achieved with non-polar organic solvents. In order to increase the extraction yields of the ionic organometallic species, complexing agents such as tropolone [5] or sodium N,N-diethyldithiocarbamate [7,8,10] are added to the sample. To make the ionic organometallic species amenable to GC they have to be converted into volatile, thermally stable compounds.…”

An analytical method for the simultaneous in situ derivatization of organotin and organolead compounds in water samples is described. Propylated derivatives of the analytes formed directly in the aqueous medium by reaction with tetrapropylborate ions are extracted by hexane/pentane. The organic layer is dried and purified with sodium sulfate, concentrated by evaporation of the solvent, and injected into a coupled gas chromatography‐atomic absorption spectrometry system. The organotin and organolead compounds are determined sequentially. The optimum parameters for the derivatization and extraction procedures of in situ butylation of organolead compounds developed earlier could be successfully applied to the in situ propylation.
