Rapid direct spectrophotometric determination of zirconium(IV) in alloys with 2,2/,3,4-tetrahydroxy-3/-sulpho-5/-carboxyazobenzene reagent
(2011)
In this study, 2, 2', 3, 4-tetrahydroxy-3'-sulpho-5'-carboxyazobenzene (tetrahydroxyazon SC) has been synthesized for the first time and used for direct spectrophotometric determination of zirconium(IV). Tetrahydroxyazon ...
Potentiometric titration of some imidazole derivatives in nonaqueous solvent
(1996)
The acidity constants of 4,5-diphenyl imidazole, 2,4,5-triphenyl imidazole, and 2,4,5-triphenyl imidazole derivatives in nitrobenzene, acetonitrile and glacial acetic acid were determined. Perchloric acid, prepared in ...
Selective photocatalytic oxidation of 4-substituted aromatic alcohols in water with rutile TiO2 prepared at room temperature
(Royal Soc Chemistry, 2009)
Home-prepared (HP) rutile TiO2 catalysts were prepared at room temperature by using H2O and TiCl4 in different ratios and without addition of additives. The catalysts were used for carrying out the selective photocatalytic ...
Environmentally Friendly Photocatalytic Oxidation of Aromatic Alcohol to Aldehyde in Aqueous Suspension of Brookite TiO(2)
(Springer, 2008)
Photocatalytic oxidation of 4-methoxybenzyl alcohol to aldehyde in water has been achieved by using home-prepared uncalcined brookite TiO(2). Three different lamp irradiances have been applied in order to check the influence ...
Süperkritik karbon dioksitte boyama
(2006)
Tekstil materyallerinin klasik yöntemlere göre boyanmasında su kullanımı ve bunun sonucunda oluşan atıksu, çevre açısından önemli bir sorundur. Çevresel sorunları önlemek için kanuni yaptırımların olması, endüstriyel ...
Performance of dye-affinity beads for aluminium removal in magnetically stabilized fluidized bed
(2004)
Background: Aluminum has recently been recognized as a causative agent in dialysis encephalopathy, osteodystrophy, and microcytic anemia occurring in patients with chronic renal failure who undergo long-term hemodialysis. ...
Latex supported manganese (III) porphyrin catalysts for oxidations of alkenes by hydrogen peroxide and tert-butyl hydroperoxide in the aqueous medium
(1996)
Cationic polymer latexes were prepared by emulsion copolymerization of vinylbenzyl chloride and divinylbenzene followed by quaternization with trimethylamine and used as catalyst supports for 5,10,15,20-tetrakis(2, ...
Graphite-supported TiO2 for 4-nitrophenol degradation in a photoelectrocatalytic reactor
(Elsevier Science Sa, 2009)
Amorphous TiO2, prepared at room temperature through a sol-gel method implementing hydrolysis of TiCl4, has been supported on graphite rods and then annealed at 673 K. In this way graphite was completely covered by a porous ...
Synthesis and antimicrobial investigation of some 5H-pyridazino[4,5-b] indoles
(2013)
Synthesis and in vitro antimicrobial activities are reported for a series of 1,3,5-substituted 4-oxo-3,4-dihydro- 5H -pyridazino[4,5- b]indole derivatives. Corresponding pyridazino[4,5- b]indoles were prepared from ethyl ...
Photocatalytic oxidation of nitrobenzene and phenylamine: Pathways and kinetics
(John Wiley & Sons Inc, 2007)
The oxidation of nitrobenzene and phenylamine has been carried out by heterogeneous photocatalysis in aqueous suspensions of commercial TiO2. The photoreactivity results indicate that two reaction pathways occur in parallel ...
