The analytical performance of three trap systems for flame AAS were evaluated for determination of Cd and Pb in waters. In addition to a water- cooled U- shaped silica trap, two other novel traps, namely, a water- cooled U- shaped silica trap combined with a slotted silica tube and a slotted silica tube trap were used. Flame alteration and organic solvent aspiration techniques were two atomization techniques introduced in this work. The slotted silica tube trap with either flame alteration or organic solvent aspiration was found to be the most sensitive, effective and simplest device. For a collection period of 2.0 min, sensitivity enhancements, compared to flame AAS, were 137 and 90 folds for Cd and Pb, respectively, using the slotted silica tube trap and organic solvent aspiration technique.

Investigations on nature of re-volatilization from atom trap surfaces in flame AAS Korkmaz, D; Kumser, S; Ertas, N; Mahmut, M; Ataman, Osman Yavuz (2002-01-01) Some experiments were designed and performed in order to elucidate the mechanism of re-volatilization in silica traps using flame AAS. A water-cooled U-shaped silica trap and a slotted silica tube trap were used, while organic solvent aspiration was employed for re-volatilization. Analytes were Bi, Au, Mn, Cd and Pb. The detailed experiments have shown that heating is not necessarily associated with re-volatilization: however, a direct contact between flame and active silica surface is required. The effect ...
Sensitive determination of bismuth by flame atomic absorption spectrometry using atom trapping in a slotted quartz tube and revolatilization with organic solvent pulse Kilinc, Ersin; BAKIRDERE, Sezgin; AYDIN, FIRAT; Ataman, Osman Yavuz (2012-07-01) Sensitivity of flame atomic absorption spectrometry (FAAS) for Bi determination was improved by slotted quartz tube (SQT) that was used also for atom trapping (AT). The trapped analyte was released by aspirating a small volume of organic solvent after a reasonable analyte collection time. Sensitivity was improved by 2.9 times by SQT-FAAS and 256 times by SQT-AT-FAAS with respect to FAAS. Optimum trapping period was found to be 6.0 min (36.0 mL of solution). Limit of detection (LOD) for SQT-AT-FAAS was found...
Characteristics of traps in AgIn5S8 single crystals Özdemir, Salahattin; Firat, Tezer (Elsevier BV, 2014-10) Characteristics of charge traps in AgIn5S8 single crystals are investigated by the use of Thermally Stimulated Current (TSC) technique. The TSC spectra of the unintentionally doped sample recorded at a constant heating rate from 80 K to 300 K reveals a single broad peak at similar to 90 K. The shift of the TSC peak continuously due to post-illumination preheating process confirmed the continuous trap distribution, which is Gaussian in shape. The trap density distribution changes from similar to 40 meV on th...
Anomalous heating rate dependence of thermoluminescence in Tl2GaInS4 single crystals DELİCE, SERDAR; Bulur, Enver; Hasanlı, Nızamı (2014-12-01) Trap centers in Tl2GaInS4 single crystals have been investigated by thermoluminescence (TL) measurements in the temperature range of 10-110 K. Curve-fitting method was utilized to evaluate the activation energies (12 and 26 meV) of revealed two trap centers. Thermal cleaning method was applied to the spectra and two overlapping peaks were reduced to one single peak corresponding to deeper trap level. The characteristics of heating rate dependence and trap distribution of the separated peak have been studied...
Sensitivity improvement for antimony determination by using in-situ atom trapping in a slotted quartz tube and flame atomic absorption spectrometry TİTRETİR DURAN, SERAP; Sik, Ahmet Inanc; ARSLAN, YASİN; Ataman, Osman Yavuz (2012-11-01) Significant improvement has been achieved for antimony determination using a slotted quartz tube (SQT) as an atom trap (AT) for in situ preconcentration and flame atomic absorption spectrometry (FAAS). The suggested technique consists of trapping analyte species during ordinary nebulization followed by releasing the collected analyte via introducing organic solvent. Procedures and analytical figures of merit have been presented for the techniques called FAAS. SQT-FAAS and finally SQT-AT-FMS with the relevan...
