Adsorption of copper(II) onto perlite
(Academic Press Inc, 2001)Perlite samples activated by H2SO4 solutions were utilized as adsorbents for the removal of Cu(II) ions from solutions at different pHs, ionic strengths, and temperatures. It has been found that the amount of Cu(II) adsorbed ... -
Adsorptive cathodic stripping voltammetric determination of antimony in the presence of copper and bismuth by using hematoxylin
(Parlar Scientific Publications (P S P),, 2014)This study describes a new adsorptive cathodic stripping voltammetric method using hematoxylin as complexing reagent for determination of antimony in the presence of Cu(II) and Bi(III). The method is based on the accumulation ... -

Determination of zineb in tap water and tomato samples by adsorptive catalytic stripping voltammetry
(Scientific Technical Research Council Turkey-Tubitak, 2013)This paper describes a sensitive and accurate adsorptive catalytic stripping voltammetric method for the determination of zineb (zinc ethylene-bis-dithiocarbamate) in tap water and tomato samples. The method is based on ... -
Dissolution kinetics of ulexite in aqueous EDTA solutions
(Metallurgical Soc-C I M, 2000)The dissolution kinetics of ulexite in aqueous disodium Ethylene Diamine Tetra Acidic Acid (EDTA) solutions has been investigated with respect to the effects of particle size, solution concentration, pH of solution, ... -
Ent-kaurane diterpenoids isolated from Sideritis congesta
(Elsevier Science Bv, 2011)A new ent-kaurane diterpenoid, together with eight known ent-kauranes, were isolated from the petroleum ether and acetone extracts of the whole plant of Sideritis congesta P. H. Davis & Hub.-Mor. and their structures were ... -
Essential oil composition of twenty-two Stachys species (Mountain tea) and their biological activities
(Elsevier Science Bv, 2011)The essential oils from twenty-two different Stachys species were obtained by hydrodistillation and analyzed by gas chromatography-mass spectrometry (GC-MS). Thirty-nine compounds, which accounted for 70.5-97.8% of the ... -
Experimental and theoretical vibrational spectra of sideridiol isolated from sideritis species
(Maik Nauka/Interperiodica/Springer, 2017)Sideridiol (ent-7 alpha,18 beta-dihydroxykaur-15-ene) one of the ent-kaurene diterpenoid, is isolated from the genus Sideritis L. belongs to the family of Lamiaceae. The vibrational frequencies of sideridiol in the ground ... -
Exploring prospective chemistry teachers' perceptions of precipitation, conception of precipitation reactions and visualization of the sub-microscopic level of precipitation reactions
(Royal Soc Chemistry, 2019)In this study, how prospective chemistry teachers (PCTs) perceive precipitation and conceptualize precipitation reactions at the symbolic level was explored. Further, it was of interest to identify PCTs' visualization of ... -
Fatty acid composition and chemotaxonomic evaluation of species of Stachys
(Taylor & Francis Ltd, 2012)The fatty acid composition of the seed oil of 23 Stachys taxa was analysed by GC/MS. The main compounds were found to be linoleic (27.1-64.3%), oleic (20.25-48.1%), palmitic (4.3-9.1%), stearic (trace to 5.2%) and ... -
Indirect determination of boron in water by cathodic stripping voltammetry
(Parlar Scientific Publications (P S P),, 2006)An indirect cathodic stripping voltammetric method for the determination of boron was described. The method is based on monitoring the peak current decrease of As(V) in the presence of mannitol, copper and selenium in ... -
Influence of constituents on thermal properties of polymethacrylate derivatives-clay materials
(Wiley-Blackwell, 2011)In this study, the solution-mixing method was used to prepare polymethacrylate derivatives' (PaMAs) nano-composites with kaolinite. It was observed that the resultant materials could include exfoliated, intercalated, and ... -
Preparation and characterization of sepiolite-poly(ethyl methacrylate) and poly(2-hydroxyethyl methacrylate) nanocomposites
(John Wiley, 2009)Poly(ethyl methacrylate) (PEMA) and poly(2-hydroxyethyl methacrylate) (PHEMA) nanocomposites with sepiolite in pristine and silylated form were prepared using the solution intercalation method and characterized by the ... -
Surface titrations of perlite suspensions
(Academic Press Inc, 1998)The surface charge behaviour of unexpanded and expanded perlite samples in KNO3 and NaCl solutions were investigated as a function of pH and ionic strength. The solutions of KNO3 and NaCl ranging from 10(-3) to 1.0 M were ... -
Undergraduate pre-service teachers' understandings and misconceptions of phase equilibrium
(Amer Chemical Soc, 2006)Some 59 pre-service chemistry teachers enrolled in physical chemistry course offered by the faculty of education at a public university in Turkey were sampled to determine possible misunderstandings about phase equilibrium ... -
Who should study music education? A vocational personality approach
(Routledge Journals, 2013)The main purpose of the current study was to examine the utility and usefulness of Holland's Theory of Personalities in Work Environments to understand the match between personality and the desire for music education. The ...
