Photoreactivity of cadmium sulfide nanoparticles as undoped and doped with manganese, nickel and copper were studied in the decolorization of methylene blue and safranin under UV and Vis irradiations. The dopant, mole fraction of dopant to cadmium ion, pH of solution, dosage of photocatalyst and concentration of dye are variables that influence on the photoreactivity of nanocatalysts. In among ...

ABOUT 30% OF INTRACELLULAR volume is made up of mitochondria, particularly in cells demanding higher energy such as cardiac myocytes and renal proximal tubules, where they serve as important “powerhouses” (3, 6). Mitochondria are integral to the maintenance of normal cellular physiology and play a central role in the processes involved in apoptosis (4–6). Changes in mitochondrial function contr...

Textile effluents are major industrial polluters because of high color content, about 15% unfixed dyes and salts. The present paper is aimed to investigate and develop cheap adsorption methods for color removal from wastewater using waste materials activated carbon and activated rice husk-as adsorbents. The method was employed for the removal of Safranin-T and the influence of various factors s...

Unmodified and gold-modified semiconductor oxides were used for the complete decolorization of non-buffered aqueous safranin O solutions. Photocatalytic properties of commercially available ZnO and TiO2 (anatase nanopowder) were compared with those of gold-modified ZnO (Au/ZnO). Au/ZnO was obtained from commercial ZnO powder through direct current sputter coating. ZnO-ba...

Safran (Crocus sativus L.) denildi?inde ?üphesiz akla ilk gelen dünyan?n en pahal? tar?m ürünü / baharat? oldu?udur. Bu ifadenin do?ru olmas?ndan kaynakl? olarak bu kadar k?ymetli bir ürüne pek çok yerinde ve kültüründe türlü de?erler yüklenmesi de normal kabul edilmelidir. Öyle ki Orta Ça?’da safranda hile yapanlar?n idamla cezaland?r?lmas?na de?in varacak ölçüde de?er görmü?tür. Safran, antik...

Abstract We report the chemical synthesis of poly( aniline-co - aniline-2,5-disulfonic acid) ) and its composite containing L-hexuronic acid metallic Ag/SiO 2 nanoparticles as a new thermally stable anionic polyelectrolyte for removing safranin dye. The was characterized by IR, UV, cyclic voltammetry, SEM, TEM, TGA, DSC, EDXS elemental analyses. Microscopic images exhibited intensified spherica...
