Introduction Dyes used in the textile industry represent a large and important group of chemicals among the different aqueous pollutants that get mixed in wastewater. The use of reactive dyes has grown rapidly due to the

Introduction Prior to 1856, dyes were prepared from natural sources such as flowers, vegetables, woods, root, insects, etc. However, with the increasing needs and demands, industries became dependent on dyes manufactured from

Abstract  

Thermal stability of silica-polyvinylsiloxane systems with different ratio of hydrophilic and hydrophobic components and its forms with adsorbed dyes were studied using thermochemical method. It was shown that the maximum of endoeffect relating to dehydroxylation of sorbents surface is observed at 325C. The maximum temperature of the second endoeffect depends on the organosilica sorbents composition and increases with a decrease of hydrophilic and hydrophobic sites ratio. It was found that the values of the summary thermal effect lowers upon the raise of the quantity of silanol groups. It was shown that thermal stability of composition materials is higher in comparison with initial organosilica sorbents.

of wastewater dyes such as coagulation, flocculation, biodegradation and oxidation are expensive and often ineffective [ 6 , 7 ]. Therefore, recent studies have been focused on application of clays as low-cost adsorbents to remove colored pollutants

Abstract  

Dyeing fibers at low temperatures has many advantages such as savings in energy and avoiding alterations to the physical properties of the fibers being dyed or other fibers also present in blends. The problem of low temperature dyeing in synthetic fibers is that it difficults the dye diffusion into the fiber. In the case of polyamide 6.6 microfibers, by using benzyl alcohol as an auxiliary dyeing, it was shown that good diffusion was obtained for the dye exhaustion with metal complex dyes at temperatures more than 30C below the normal dyeing temperature for the dye exhaustion with metal complex dyes. Using thermal analysis methods these results were shown to be caused by the lowering of the T g of the fiber when in the presence of benzyl alcohol.
