(2005)
Bu çalışmada kolon yöntemi kullanılarak Fe{2} iyonlarının Saccharomyces cerevisiae immobilize edilmiş ponza taşına adsorpsiyon şartları araştırıldı. Bu amaçla; adsorpsiyona çözelti pH sının, iyon başlangıç derişiminin ve ...
Adsorption behaviour of copper(II) ion from aqueous solution on 4-vinyl pyridine grafted poly(ethylene terephthalate) fibers
(2002)
The adsorption behaviour of 4 vinyl pyridin grafted poly (ethylene terephthalate) fibers was studied towards the copper (II) ions in aqueous solutions by a batch equilibriation technique. The influence of treatment time, ...
Adsorption behaviour of copper (II) ion from aqueous solution on poly(4-vinyl pyridine)
(2002)
The adsorption behaviour of poly(4 - vinyl pyridine) towards copper (II) ion in aqueous solutions was studied by a batch equilibriation technique. Influence of treatment lime, pH of the solution and metal ion concentration ...
The investigation of the pore structure of fine alumina powders prepared for ceramic production by the technique of precipitation from solution
(2000)
In this study, alumina precursors were prepared in three different ways and were converted into three different alumina powders (Al2O3) by calcination. The precipitation methods of the alumina precursors were as follows: ...
Chemoenzymatic synthesis of 2-brorno-6-hydroxy-3-methoxy-2-cyclohexen-1-one
(Scientific Technical Research Council Turkey-Tubitak, 2007)
A chemoenzymatic synthesis of 2-bromo-6-hydroxy-3-methoxy-2-cyclohexen-1-one starting from cyclohexane-1,3-dione is reported. Manganese (III) acetate-mediated acetoxylation followed by the enzyme-mediated hydrolysis of ...
Application of FAM ligands in the metal-promoted catalytic enantioselective synthesis of organic compounds
(Scientific Technical Research Council Turkey-Tubitak, 2009)
Novel ferrocenyl substituted aziridinyl methanol (FAM) ligands were synthesized and successfully used in metal-promoted catalytic enantioselective azomethine ylide cycloadditions, diethylzinc additions to enones, alkynylzinc ...
