A reservoir type of optode is described for simultaneous and remote determination of Cd and Zn using [9-(1',4',7', 10',13'-pentaazacyclopentadecyl)methylanthracene] as the fluorophore. Simultaneous analysis was achieved by the significant perturbation in the fluorescence spectrum of the Cd-ligand complex while the Zn complex only results in enhancement in the fluorescence intensity as compared to ligand alone. The ion permeability of several membranes were examined; Nafion and cellophane were used for the construction of the optode. Using the optode constructed with cellophane, for 20 min immersion time, the 3-s detection limits were found to be 4.5 mu g l(-1) for Cd and 0.6 mu g l(-1) for Zn.

Simultaneous determination of Cd and Zn by fluorescence spectrometry using a novel reagent and surfactants Ertas, N; Akkaya, EU; Ataman, Osman Yavuz (1997-01-01) A method for the simultaneous determination of zinc and cadmium with the chelating ligand 9-(1',4',7',10'-Tetraazacyclododecyl)methylanthracene using spectrofluorimetry is described. Effect of experimental variables on fluorescence intensities and on the spectral behavior of the metal-ligand in several types of surfactants have been studied, The range of application is between 2.0 and 35 mu g/L for both zinc and cadmium. The method has been applied to the determination of zinc and cadmium in real leachate s...
Interference studies in slotted silica tube trap technique Korkmaz, D; Mahmut, M; Helles, R; Ertas, N; Ataman, Osman Yavuz (2003-01-01) Interference effects of KCl, NH4H2PO4, (NH4)(2)CO3, MgCl2, NH4NO3, NaNO3, (NH4)(2)SO4, MgSO4.7H(2)O, CaCl2, Ca(NO3)(2) and NaCl on Bi, Cd, In, Pb and Sb were investigated using the atom trapping technique with a double slotted silica tube. Analyte solutions at concentration levels of 60, 6, 300, 75, 100 ng mL(-1) for Bi, Cd, In, Pb and Sb, respectively, were aspirated into an air-acetylene flame and analyte species were collected on the silica surface. Revolatilization was effected by aspirating IBMK at the...
SPECTROSCOPIC INVESTIGATION OF PYROLYSIS PRODUCTS OF SOME POLYSTYRENES ORHAN, BO; YALCIN, T; SUZER, S (1992-03-01) An investigation of the pyrolysis products of some polystyrenes prepared by different methods is performed by Mass and IR spectroscopic techniques over the temperature range 30-450-degrees-C. Main pyrolysis product of the polystyrene samples obtained by a free radical initiator and gamma-rays is found to be styrene; whereas, toluene, ethylene and methane are observed as the pyrolysis products of plasma initiated polystyrene. The results demonstrate the dependence of pyrolysis products on polymer structure.
Measurement of the inelastic proton-proton cross section at root s=13 TeV Sirunyan, A. M.; et. al. (Springer Science and Business Media LLC, 2018-07-01) A measurement of the inelastic proton-proton cross section with the CMS detector at a center-of-mass energy of root s = 13 TeV is presented. The analysis is based on events with energy deposits in the forward calorimeters, which cover pseudorapidities of -6.6 4.1 GeV and/or M-Y > 13 GeV, where M-x and M-Y are the masses of the diffractive dissociation systems at negative and positive pseudorapidities, respectively. The results are compared with those from other experiments as well as to predictions from hi...
Simultaneous determination of selected endocrine disrupter compounds in wastewater samples in ultra trace levels using HPLC-ES-MS/MS Komesli, Okan Tarik; Bakirdere, Sezgin; Bayoren, Ceren; Gökçay, Celal Ferdi (2012-08-01) An analytical procedure for the simultaneous determination of six selected endocrine disrupter compounds (EDCs: diltiazem, progesterone, benzyl butyl phthalate (BBP), estrone, carbamazepine (Cbz), acetaminophen) was developed by liquid chromatography electrospray ionization tandem mass spectrometry (HPLC-ES-MS/MS). All of the parameters for HPLC and ES-MS/MS systems including mobile phase composition, flow rate, and sample injection volume were optimized to obtain not only the best separation of species int...
