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.

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...
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...
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.
Excitation and temperature tuned photoluminescence in Tl2In2S3Se layered crystals
Güler, Işıkhan; Hasanlı, Nızamı (2006-12-01)
Photoluminescence spectra of Tl2In2S3Se layered single crystals have been studied in the wavelength region of 535-725 nm and in the temperature range of 22-58 K. Two photoluminescence bands centered at 564 (2.20 eV, A-band) and 642 nm (1.93 eV, B-band) were observed at T = 22 K. Variations of both bands have been investigated as a function of excitation laser intensity in the range from 16 to 516 mW cm(-2). These bands are attributed to recombination of charge carriers through donor-acceptor pairs located i...
