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 muL level. A method was proposed to classify interferences as the types of condensed phase or gas phase. In case of high NaCl content in the sample matrix, devitrification of the silica surface is a problem.

Thermal degradation of polystyrene composites. Part I. The effect of brominated polyepoxy and antimony oxide Kaya, Hatice; Hacaloğlu, Jale (2014-01-01) Thermal degradation of polystyrene (PS) involving brominated polyepoxy (BA) and antimony oxide (PS/BE/Sb2O3) was studied systematically via direct pyrolysis mass spectrometry. Thermal decomposition of brominated polyepoxy was started by loss of end groups. The relative yields of high mass thermal degradation products of PS and the product distribution of brominated polyepoxy and antimony oxide were changed noticeably during the pyrolysis of PS/BE/Sb2O3 composite. Its thermal decomposition was initiated by t...
Thermal decomposition of glycidyl azide polymer by direct insertion probe mass spectrometry Fazlioǧlu, Hatice; Hacaloğlu, Jale (2002-01-01) Thermal decomposition reactions and products of glycidyl azide polymer (GAP), have been investigated by direct insertion mass spectrometry and evolved gas analyses by FTIR spectroscopy techniques. It has been observed that thermal degradation of GAP begins with cleavage of the side groups. Although the main decomposition started with the elimination of molecular nitrogen from the azide functional group, degradation initiated by loss of N-3 and CH2N3, depolymerization type reactions were also identified. Rea...
Conducting polymers of succinic acid bis-(2-thiophen-3-yl-ethyl)ester and their electrochromic properties SACAN, L; Çırpan, Ali; CAMURLU, P; Toppare, Levent Kamil (Elsevier BV, 2006-02-01) The homopolymer and copolymer of succinic acid bis-(2-thiophen-3-yl-ethyl)ester with thiophene were achieved via constant potential electrolysis in the presence of tetrabutylammonium tetrafluoroborate as the supporting electrolyte, and acetonitrile/borontrifluoride ethylether (ACN/BFEE) (10:2 v/v) solvent mixture. The characterizations of both homopolymer (PSATE) and copolymer P(SATE-co-Th) were achieved by various techniques including cyclic voltammetry (CV), Fr-IR, scanning electron microscopy (SEM) and U...
Thermal decomposition of polystyrene-b-poly(2-vinylpyridine) coordinated to co nanoparticles Elmaci, Ayşegül; Hacaloğlu, Jale; Kayran, Ceyhan; Sakellariou, Georgios; Hadjichristidis, Nikos (2009-11-01) Direct pyrolysis mass spectrometry analyses of polystyrene-block-poly(2-vinylpyridne), PS-b-P2VP, indicated that the thermal degradation of each component occurred independently through the decomposition pathways proposed for the corresponding homopolymers; depolymerization for PS and depolymerization and loss of protonated oligomers for P2VP by a more complex degradation mechanism. On the other hand, upon coordination to cobalt nanoparticles, thermal decomposition of the P2VP blocks was initiated by loss o...
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...
