Self-assembled titania-silica-sepiolite based nanocomposites for water decontamination
(Royal Soc Chemistry, 2009)
This work describes the preparation of microchannel structured monolithic pieces by the "ice-segregation induced self-assembly'' (ISISA) process. The monoliths exhibit a hierarchical structure composed of homogeneously ...
Determination of naproxen in tablets by using first derivative potentiometry
(2004)
Bu çalışmada, naproksen sodyumun potansiyometrik tayini tanıtılmaktadır. Naproksenin tayini için en iyi çözücü sistemi, sodyum klorür ilavesiyle 0,1 iyonik şiddete ayarlı % 20 etanol (h/h) olarak bulundu. Aktif maddenin ...
Photocatalytic oxidation of aromatic alcohols to aldehydes in aqueous suspension of home-prepared titanium dioxide 1. Selectivity enhancement by aliphatic alcohols
(Elsevier Science BV, 2008)
Oxygenated aqueous suspensions of home-prepared (HP) and commercial TiO2 catalysts were used in a batch photoreactor for carrying out the oxidation of benzyl alcohol (BA) and 4-methoxybenzyl alcohol (MBA) under different ...
Selective separation of thiocyanate ion by ion-imprinted polymer
(2009)
Molecular imprinting is a emerging technology to create recognition sites in a polymeric matrix using a molecular template. The molecularly imprinted polymers (MIPs) are easy to prepare, stable, inexpensive and capable of ...
Photocatalytic degradation of 4-nitrophenol in a continuous reactor containing titanium dioxide supported on glass beads
(Walter De Gruyter GMBH, 2008)
The photocatalytic degradation of 4-nitrophenol in aqueous solution was per-formed by using a continuous fixed bed annular photoreactor. Titanium dioxide was used as the photocatalyst, supported as thin film on Pyrex glass ...
Photocatalytic selective oxidation of 4-methoxybenzyl alcohol to aldehyde in aqueous suspension of home-prepared titanium dioxide catalyst
(Wiley-V C H Verlag GMBH, 2007)
The photocatalytic oxidation of 4-methoxybenzyl alcohol to p-anisaldehyde (PAA) was performed in water with organic-free suspensions of home-prepared and commercial titanium dioxide (TiO2) catalysts. The nanostructured ...
Ion-imprinted thermosensitive polymers for $Fe^ {3+}$ removal from human plasma
(2008)
Thermosensitive gels have attracted a great deal of attention for the applications of drug delivery systems, actuators, separation and removal of biological compounds and metals. Poly(N-isopropylacrylamide) (poly(NIPA)), ...
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 ...
