Experimental investigation of the agitation of complex fluids Yazıcıoğlu, Özge; Uludağ, Yusuf; Department of Chemical Engineering (2006) In this study, agitation of solutions using different impeller and tank geometry were investigated experimentally in terms of hydrodynamics, macromixing time and aeration characteristics. In the first set of experiments a cylindrical vessel equipped with two types of hydrofoil and a hyperboloid impeller or their combinations were used. Vessel and impeller diameters and water level were 300, 100 and 300 mm, respectively. At the same specific power consumption, 163 W/m3, the so called “hydrofoil 1” impeller p...
Polarographic determination of Pb(II) and Cd(II) with selective removal of Se(IV) using ionic poly(N,N-dimethylacrylamide-co-allylthiourea) Inam, R; Caykara, T; Özcan Kabasakal, Süreyya; Yagmur, M (Springer Science and Business Media LLC, 2005-12-01) 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 ...
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...
Fluorescence determination of monosaccharides and catecholamines by using dansylaminophenyl boronic acid Seçkin, Z. Ebru; Volkan, Mürvet; Department of Chemistry (2004) In sugar industry, determination of invert sugars (fructose and glucose) provides information about the quality, process control and characteristics of the produced fructose and glucose syrups. Determination of invert sugar is also important for wine industries. In wine process, fructose and glucose are converted to ethanol by fermentation and the type of wine is designated by the amount of invert sugar remained. Fast and reliable invert sugar detection techniques are required to check the quality of wine t...
Immobilization studies utilizing solid supports for the determination of fructose by dansylaminophenyl boronic acid (DAPB acid) and chromate by diphenylcarbazide (DPC) Bulut, Mukadder; Volkan, Mürvet; Department of Chemistry (2006) Immobilization of fluorescent chemosensors and chromogenic reagents on solid supports for developing optical sensors result in improved analytical performance characteristics such as continuous read-out, increased sensitivity, lower reagent consumption and possibility of using the sensor in solvents where the free molecule displays low solubility. The aim of this study is to immobilize dansylaminophenyl boronic acid (DAPB acid) and diphenylcarbazide (DPC) into various solid supports for the determination of...
