cotton/polyester knitted fabrics as a major production of textile industry was treated with titanium dioxide nanosized particles. the treated fabric with nanosized tio2 became whiter with a good self-cleaning property. also the discoloration of reactive black 5 dye was studied and reported. the stabilization of tio2 on cotton/polyester knitted fabrics by citric acid (ca) with sodium hypophospha...

The potential feasibility of anionic clay hydrotalcite for removal of eriochrome black dye from aqueous solution was investigated. The effects of various experimental parameters such as contact time, pH and adsorbent dosage were investigated. The extent of eriochrome black dye removal increased with the increased in contact time, pH and amount of adsorbent used. Adsorption data was fitted to th...

as dyes are the most important pollutants of many industrial wastewaters. a large amount of reactive black 5 enters the environment in iran because of the use of this dye in iran's textile industries, so the goal of this study was to survey the catalytic ozonation process with bone char in removal of reactive black 5 dye from synthetic wastewater. in this experimental study bone char (bc) was p...

The arrays of artificial receptors were synthesized and used in the studies of binding of triphenylmethyl dyes. Rate of binding of Brilliant Black was determined by the measurements of decrease of optical density of dye solution. Considering the fast process of removing excess of dye and uniform coloration of receptors, Brilliant Black was evaluated as the most versatile reporter dye for Indica...

Previous studies suggest that reactive dyes can induce IgE mediated bronchoconstrictions. To evaluate the significance of specific IgE and IgG antibodies in workers exposed to reactive dyes, we studied the prevalence of Black GR-specific IgG by enzyme linked immunosorbent assay, as well as Black GR-specific IgE by RAST, in 176 workers employed in 1 reactive dye factory and 4 neighboring factori...

Background and purpose: Generated dye wastewater by the textile industry is usually toxic, non-biodegradable and resistant in the environment. Eggshell is one of the inexpensive material and for the reason the vesicular structures can be used as a proper adsorbent for pollutants removal. The aim of this study is to investigate the efficiency of eggshell for removal of acid orange 2 dye from aqu...

industrial wastewater included the dyes one of the important sources of environmental pollution that founded in loom wastewater which are harmful for human health and environment. therefore, the purpose of this research was investigated removal of rb5 dye from aqueous solution by using of adsorption onto activated red mud as an cheap adsorbent. this research was experimental- laboratorial study...

a comparison of the photoefficiency of ni(ii) and nis incorporated into zeolite p towards photodecolorization of eriochrome black t dye solution was investigated in a photocatalytic reactor using uv lamp as a light source. the effect of various experimental variables on the decolorization performance of the process was evaluated by examining catalyst dosage, temperature, initial dye concentrati...

A screening using several laccase mediators (2,2-azinobis(3ethylbenzthiazoline-6-sulfonic acid (ABTS), 1-hydroxybenzotriazole (HBT), Nhydroxyacetanilide (NHA), 2,2,6,6-tetramethylpiperidin-1-yloxy (TEMPO) and violuric acid (VA)) was performed on the degradation of three reactive textile dyes: Reactive Black 5 (RB5), Reactive Blue 114 (RB114) and Reactive Yellow 15 (RY15). ABTS was the most effe...
