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. ...
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 ...
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 ...
Home-prepared anatase, rutile, and brookite TiO2 for selective photocatalytic oxidation of 4-methoxybenzyl alcohol in water: reactivity and ATR-FTIR study
(Royal Soc Chemistry, 2009)
TiO2 catalysts of anatase, rutile and brookite phase were prepared at low temperature and tested for carrying out the photocatalytic partial oxidation of 4-methoxybenzyl alcohol to 4-methoxybenzaldehyde (p-anisaldehyde) ...
Preparation of new molecularly imprinted quartz crystal microbalance hybride sensor system for 8-hydroxy-2 '-deoxyguanosine determination
(Elsevier Science BV, 2009)
The routine measurement of 8-hydroxy-2'-deoxyguanosine (8-OHdG) in biological samples is a difficult analytical problem due to the low levels of the analyte and complex matrix. A new 8-OHdG imprinted quartz crystal ...
Structural studies of water-soluble ß-brominated manganese porphyrins: Stabilities of MnTDCSPPBr8 and MnTSPPBr8 as homogeneous and supported reagents toward hydrogen peroxide and sodium hypochlorite
(2001)
This article describes the structural stabilities of [2,3,7,8,12,13,17,18-octabromo-5,10,15,20-tetrakis(2,6-dichloro-3- sulfonatophenyl)porphinato]manganese(III) X (where X = H2O and/or OH-, depending on pH) (MnTDCSPPBr8) ...

Separation of catechins and methylxanthines in tea samples by capillary electrochromatography
(2009)
In this paper, the simultaneous separation of several polyphenols such as (+)-catechin, (-)-epicatechin, (-)-epigallocatechin, theophylline, caffeine in green and black teas by capillary electrochromatography (CEC) was ...
A quantitative method of photoadsorption determination for irradiated catalyst in liquid-solid system
(Elsevier Science BV, 2009)
A method for determining the amount of substrate adsorbed onto the catalyst surface in liquid-solid photocatalytic system under reaction conditions (photoadsorption) is proposed. The method has been applied to the ...
