Mercury speciation in aqueous solutions containing inorganic mercury and methylmercury has been demonstrated using electrochemical separation prior to determination by cold-vapour atomic absorption spectrometry. Approximately 95% of the inorganic mercury was electro-deposited on a Pt electrode at –0.1 V, whereas for methylmercury –0.2 V or even more negative potentials were required. Organic mercury was determined by NaBH4 reduction after electrochemical separation. Inorganic mercury was determined in the original solution by SnCl2 reduction.

Historical development of simulated body fluids used in biomedical applications: A review
Yilmaz, Bengi; Pazarçeviren, Ahmet Engin; Tezcaner, Ayşen; Evis, Zafer (Elsevier BV, 2020-06-01)
Simulated body fluid (SBF) is an acellular, protein-free, supersaturated calcium-phosphate solution with ionic composition nearly equal to that of human blood plasma and generally buffered at physiological conditions (pH 7.4 and 36.5 degrees C). Various SBF formulations have been used for decades to: (1) test corrosion and bone-bonding behavior, bioactivity, ion release, swelling and biodegradation rates of biomaterials and (2) deposit calcium phosphates, especially hydroxyapatite, onto the substrates of di...
Optimization of ETV-ICP(TOF)MS and transient signal profiles for reducing isobaric interferences
Ertaş, Gülay (Royal Society of Chemistry (RSC), 2005-01-01)
One of the advantages of the ETV sample introduction is the ability to temporally separate analyte elements in complex mixtures by differences in their vaporization temperatures within the ETV for ICPMS. However, the broadening of the transient peaks in the transport tubing often obscures this temporal resolution. This study shows that decreasing the transport tubing diameter produces little broadening beyond that produced during aerosol production in the ETV. Maintaining such narrow peaks through the trans...
Vibrational frequencies studied as a function of pressure in phase II of solid benzene
Yurtseven, Hasan Hamit; Kilit, E. (Elsevier BV, 2011-05-03)
The pressure dependence of the vibrational frequencies of six Raman modes is analyzed in phase II of solid benzene. The frequency shifts 1/nu(partial derivative nu/partial derivative P)(T) of those Raman modes are deduced from this analysis and they are related to the isothermal compressibility kappa(T)= -(1/V)(partial derivative V/partial derivative P)(T) through a constant isothermal mode Gruneisen parameter gamma(T) in phase II of solid benzene. The kappa(T) values predicted here are compared with the ka...
Thin-film microextraction coupled to LC-ESI-MS/MS for determination of quaternary ammonium compounds in water samples
Boyacı, Ezel; Pawliszyn, Janusz (Springer Science and Business Media LLC, 2014-01-01)
The dual nature of the quaternary ammonium compounds, having permanently charged hydrophilic quaternary ammonium heads and long-chain hydrophobic tails, makes the sample preparation step and analysis of these compounds challenging. A high-throughput method based on thin-film solid-phase microextraction (SPME) and liquid chromatography mass spectrometry was developed for simultaneous quantitative analysis of nine benzylic and aliphatic quaternary ammonium compounds. Chromatographic separation and detection o...
Hydrogen sulfide determination by solid surface luminescence
Eroglu, AE; Volkan, Mürvet; Bayramh, E; Ataman, Osman Yavuz; Mark, HB (1996-07-01)
In the analytical system suggested, atmospheric hydrogen sulfide reacts with the surface of a filter paper treated with aqueous cadmium chloride and yields a luminescent species whose intensity can be correlated with the analyte concentration in ambient air. It was shown that the luminescent species are CdS solid particles which were formed in a well defined size. The paper luminescence was also tried on polymeric surfaces; polyethyleneoxide, polyvinyl alcohol, ethylcellulose and carboxymethylcellulose were...
