OBJECTIVES Some patients with occupational asthma resulting from exposure to reactive dyes have skin reactivity to the causative dyes and specific IgE to reactive dyes have been found in these patients. However, the usefulness of skin prick tests (SPTs) and serological measurement of specific IgE in screening, diagnosis, and monitoring the occupational asthma resulting from exposure to reactive...

    Background & Aims of the Study: Textile wastewaters are very various in chemical qualities. In other words, these industries are one of the largest producing dyes compounds; therefore their treatment is so complex and difficult. The aim of this study was to evaluate the potential removal of Reactive Red 198 and Blue Reactive 19 from synthetic solution by Acaciatortilis shu...

the rate and efficiency of decolorization of dyes likeblue ca, black b133, and corazol violet sr were tested to evaluate white rot fungal strains. trametes hirsuta and pleurotus florida showed the greatest extent ofdecolorization on nutrient salt media. maximum decolorization of 200 mg/l of blue 133 was obtained by 4days old incubated pleurotus florida followed bytrametes hirsuta after 6 days. ...

Seven reactive dyes judiciously selected based on chemical structures and fixation mechanisms were applied at 2% of of shade on amidoximated acrylic fabrics. Amidoximated acrylic fabric has been obtained by a viable amidoximation process. The dyeability of these fabrics was evaluated with respect to the dye exhaustion, fixation, and colour strength under different conditions of temperature and ...

Introduction: Several new bifunctional reactive dyes of the Sumifix Supra range that carry monochlorotriazine and sulphato ethyl sulphone reactive systems were developed and their dyeing performance studied. Suitable characteristic properties and fastness properties were examined over the knitted cotton fabrics. The dyes were characterized by spectral data and elemental analysis. The dyes struc...

textile effluents contain different kinds of chemical dyes and many mutagenic and carcinogenic substances. discharge of these effluents into terrestrial and aquatic ecosystems causes harmful effects. in this research, decolorization of a textile effluent by nineteen different strains of fungi was investigated. removal activity of dyes was in order of   aspergillus > rhizopus > fuzarium > penici...

Activated carbon prepared from Euphorbia tirucalli L wood (ETAC) by chemical activation with phosphoric acid has been analysed for the removal of Reactive Red and Reactive Blue dyes from aqueous solutions through batch adsorption technique. Lower solution pH favours the adsorption of reactive dyes. The amount of dye adsorbed per unit mass of adsorbent increases with the increase in temperature ...

introduction: the powdered activated carbon treatment (pact) has been proposed as an alternative in wastewater treatment and wastewater biomass protection against toxic substances. this study aims to evaluate pact performance in treating dyes, acid orange, and remazol brilliant reactive blue. methods: this empirical- applied research was carried out in pilot scale in which different dye removal...
