Hydrogels based on N,N-dimethylacrylamide (DMAAm), allylthiourea (ATU), and maleic acid (MA) were synthesized by free-radical cross-linking copolymerization in water with N,N-methylene-bis(acrylamide) (BAAm) as the cross-linker, ammonium persulfate (APS) as the initiator, and N,N,N',N'-tetramethyl-enediamine (TEMED) as the activator. Since Se(IV) is the most serious interfering element in the electroanalytical (polarographic or voltammetric) determination of lead and cadmium, a new method for their correct determination after selective separation of the interfering ion (selenite) was developed by using poly(N,N-dimethylacrylamide-co-allylthiourea) [P(DMAAm-co-ATU)] hydrogels containing reducing pedant groups like allylthiourea. The proposed method showed good reproducibility and accuracy with relative standard deviations of 8.5 and 3.4% and relative errors of -6.0 and -5.4% for the determination of 5.0 x 10(-5) M Pb(II) and Cd(II), respectively, next to 3.0 x 10(-5) M Se(IV).

Electrochemical and optical properties of novel terthienyl based azobenzene, coumarine and fluorescein containing polymers: Multicolored electrochromic polymers
Yigit, Deniz; Udum, Yasemin Arslan; GÜLLÜ, Mustafa; Toppare, Levent Kamil (Elsevier BV, 2014-01-01)
Three electroactive terthienyl based monomers, namely 1-phenyl-2-[4-(2,2':5',2 ''-terthien-3'-ylmethoxy)phenyl]diazene (TTAz), 4-(2,2':5',2 ''-terthien-3'-ylmethoxy)-2H-chromen-2-one (TTCo) and methyl 2-[3-oxo-6-(2,2':5',2 ''-terthien-3'-ylmethoxy)-3H-xanthen-9-yl] benzoate (TTFlo), were synthesized with good yields and their conducting polymers were electrochemically prepared on ITO electrode surfaces. The effect of chromophore type on electrochemical and optical properties of the polymers was investigated...
Eriochrome Black T-Eu3+ Complex as a Ratiometric Colorimetric and Fluorescent Probe for the Detection of Dipicolinic Acid, a Biomarker of Bacterial Spores
Yilmaz, M. Deniz; Öktem, Hüseyin Avni (American Chemical Society (ACS), 2018-03-20)
A novel ratiometric colorimetric and fluorescent dual probe based on Eriochrome Black T (EBT) Eu3+ complex was designed to detect dipicolinic acid (DPA), a major constituent of bacterial spores, with high sensitivity and selectivity. UV vis titration experiments demonstrated that EBT and Eu3+ ions formed a 1:1 coordination pair in water. In the presence of Eu3+ ions, the blue solution of EBT changed to magenta, however, upon the addition of DPA, the magenta color changed to blue immediately and characterist...
Atorvastatin-loaded SBA-16 nanostructures: Synthesis, physical characterization, and biochemical alterations in hyperlipidemic rats
Sayadi, Khalilolah; Rahdar, Abbas; Hajinezhad, Mohammad Reza; Nikazar, Sohrab; Susan, Md Abu Bin Hasan (Elsevier BV, 2020-02-15)
Mesoporous Santa Barbara Amorphous-16 (SBA-16) silica was synthesized via facile sol-gel method and functionalized using a silanizing agent, 3-amino-propyl-triethoxysilane, cyanuric chloride and dopamine. SBA-16/dopamine was characterized for the structure and morphology by x-ray diffraction, transmission electron microscopy, thermogravimetric analysis, and Fourier-transform infrared spectroscopy. Silica was amorphous in nature. Analysis of SBA-16 silica by Brunauer-Emmett-Teller (BET) method indicated that...
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...
Electrochemical and quantum chemical studies on mitomycin and adriamycin
Ozalp-Yaman, S; Önal, Ahmet Muhtar; Turker, L (Elsevier BV, 2003-06-25)
In-situ spectroelectrochemical redox behaviour of two prominent chemotherapeutic agents, mitomycin and adriamycin were studied at constant potential. AM 1 (UHF) type quantum chemical calculations on the neutral as well as radical anion and cation forms of mitomycin and adriamycin were performed.
