“…The electrochemical doping/undoping features of certain conducting organic polymer electrodes could be advantageous as SPME films for the preconcentration and matrix separation of anionic, 9-11 cationic [11][12][13] and neutral analytes. 14,15 Polypyrrole and its derivatives have attracted great interest in the development of electrochemically switched solid-phase microextraction (ES-SPME) as ion-exchange material for charged species. [16][17][18] The main advantage of using conducting polymers in SPME is that the charge of the coatings can be readily controlled by the oxidation and reduction of the polymers.…”

A nanostructure fiber based on conducting polypyrrole synthesized by an electrochemical method has been developed, and used for electrochemically switching solid-phase microextraction (ES-SPME). The ES-SPME was prepared by the doping of eriochrome blue in polypyrrole (PPy-ECB) and used for selectively extracting the Ni(II) cation in the presence of some transition and heavy metal ions. The cation-exchange behavior of electrochemically prepared polypyrrole on stainless-steel with and without eriochrome blue (ECB) dye was characterized using ICP-OES analysis. The effects of the scan rate for electrochemical synthesis, uptake and the release potential on the extraction behavior of the PPy-ECB conductive fiber were studied. Uptake and release time profiles show that the process of electrically switched cation exchange could be completed within 250 s. The results of the present study point concerning the possibility of developing a selective extraction process for Ni(II) from waste water was explored using such a nanostructured PPy-ECB film through an electrically switched cation exchange.

Applications of solid phase microextraction for the determination of metallic and organometallic speciesThis paper reviews recent developments of solid phase microextraction (SPME) and its application to the analysis of organometallic species of lead, arsenic, mercury, tin, and selenium by hyphenation with HPLC-GC-atomic spectrometry. In the first part, a background of the technique is given in terms of derivatization, fibers used, extraction and desorption conditions. The second part summarizes typical SPME applications to the determination of organometallic species and the main experimental conditions with the aid of specific examples. Most of the applications comprise alkylation with NaBEt 4 and headspace extraction followed by gas chromatographic separation with a suitable detector.

“…The EC-SPME with modified solid phase electrodes has been employed for detecting the cations [27][28][29] and anions (chloride, nitrite, bromide, nitrate, sulfate, and phosphate). PPY with small counter-ions, e.g., Cl − , ClO 4 − , and NO 3 − , mainly exhibits an anion exchanger behavior due to the high mobility of these ions in the polymer matrix [30].…”

Nanostructured polypyrrole for automated and electrochemically controlled in-tube solid-phase microextraction of cationic nitrogen compounds

et al. 2015

The authors describe an efficient method for microextraction and preconcentration of trace quantities of cationic nitrogen compounds, specifically of anilines. It relies on a combination of electrochemically controlled solid-phase microextraction and on-line in-tube solid-phase microextraction (SPME) using polypyrrole-coated capillaries. Nanostructured polypyrrole was electrically deposited on the inner surface of a stainless steel tube and used as the extraction phase. It also acts as a polypyrrole electrode that was used as a cation exchanger, and a platinum electrode that was used as the anode. The solution to be extracted is passed over the inner surface of the polypyrrole electrode, upon which cations are extracted by applying a negative potential under flow conditions. This method represents an ideal technique for SPME of protonated anilines because it is fast, easily automated, solvent-free, and inexpensive. Under optimal conditions, the limits of detection are in the 0.10-0.30 μg L‾ 1 range. The method works in the 0.10 to 300 μg L‾ 1 concentration range. The inter-and intra-assay precisions (RSD%; for n=3) range from 5.1 to 7.5 % and from 4.7 to 6.0 % at the concentration levels of 2, 10 and 20 μg L‾ 1 , respectively. The EC-in-tube SPME method was successfully applied to the analysis of methyl-, 4-chloro-, 3-chloro and 3,4-dichloroanilines in (spiked) water samples.
