	abstract = {The adsorption of various physical forms of dioleoyl phosphatidylcholine (DOPC) onto a Hg electrode have been studied. The three systems investigated were adsorption of DOPC from the monolayer state present on the gas \ solution (G \ S) interface, the adsorption of 100 nm DOPC liposomes present in the electrolyte, and a mixed system consisting of the co-adsorption of the monolayer and liposomes. The adsorption was characterized by capacitance measurements, chronoamperometry and impedance spectroscopy. The adsorbed layer produced by liposome adsorption was distinctly different as compared to the layer adsorbed from the G \ S interface, whereas the co-adsorbed layer retained most of the liposome layer qualities. A low capacitance region, centered at - 0.40 V (SCE) with values of 1.85, and 1.45 muF cm(-2) for the G \ S and the liposome system were, respectively observed. This region was stable with respect to very negative potential cycling only for the liposome systems. Three phase transitions (denoted by pseudo-capacitance peaks) were noted for the three systems under study; two corresponding to a change in the adsorbed state, and one corresponding to the adsorption-desorption process. The kinetics of these changes were quite different and depended on the nature of the adsorbing species. The most significant differences were observed when measuring the capacity over a large range of perturbation frequency. At low frequencies, desorption of the DOPC layer was observed at very negative potentials for all the systems studied. As the perturbation frequency was increased, the capacitance measured for the G \ S system maintained this characteristic, but surprisingly this was not the case for the liposome systems. In both cases (liposome and co-adsorbed) the capacity, calculated assuming a series RC circuit, was found to be significantly lower than the capacity measured for the Hg \ 0.1 M KCl interface. Preliminary impedance spectra are presented illustrating the non-ideal behavior of the liposomal system. This phenomenon is undergoing further study. A possible mechanism for the adsorption of DOPC from the liposomal state is also presented. (C) 2001 Elsevier Science B.V. All rights reserved.},

In respect to the determination of aqueous samples, this instrumental technique is combined with sample derivatization by the hydride generation technique. Volatile species of As, Sb, Sr and I could be detected in gases over hot springs in British Columbia (Canada). Methylated species of Hg, Ge, As, Sb and Te were also determined in concentrations in the ng/kg- to low mu g/kg-range in geothermal waters from Ruapehu, Waimangu, Waiotapu and Tokaanu (North Island, New Zealand); up to 1\% of the total dissolved metal(loid)s are found in methylated forms. Volatile metal(loid)organic species of geogenic origin are compared with those emanating from anthropogenic sources (waste and sewage gases, river and harbor sediments). Possible formation mechanisms for these compounds are discussed. (C) 1998 Elsevier Science Ltd. Ail rights reserved.},

	abstract = {A new continuous hydride generator is described. Its characteristics are compared with a conventional hydride generator for the determination of arsenic, antimony and tin by using flame atomic absorption spectrometry. This simple hydride generator combines hydride production and gas-liquid separation in one unit, obviating the use of a separate mixing/reaction coil and gas-liquid separator. Radioactive tracer studies show that a hydride generation efficiency of over 95\% is achieved with the new hydride generator and that approximately 90\% of monomethylarsonic acid (MMA) is converted to its hydride (methylarsine) within the first 10 s of the hydride generation reaction. Compared to a conventional hydride generator, an improved signal-to-noise ratio is achieved and comparable or less interference from transition metal ions is observed. Cysteine (1\% in the sample solution) is effective in reducing interferences during the hydride generation processes. In the presence of cysteine, 10-1000 fold higher amounts of Ni2+, Co2+ and Cu2+ are tolerated in the determination of arsenic, antimony and tin. Cysteine also enhances the signals of arsenic, antimony and tin by 60, 200 and 40\%, respectively. Reaction conditions were optimized by using both the simplex optimization method and one-factor-at-a-time method and results are in good agreement.},
