چکیده

Reactive dyes have been used in the textile industry for the past 60 years; they colour fibres brightly and are highly wetfast. They consist of a direct colourant (an azo, anthraquinone or phthalocyanin derivative group) connected to a reactive group, which is capable of linking through covalent bonds to the amine or sulfhydryl groups of proteins (1). We report a case of a delayed contact hypersensitivity reaction to reactive dyes.

Asthma, rhinitis, and dermatitis in workers exposed to reactive dyes.

A survey was conducted at 15 textile plants with dyehouses in western Sweden. Employees with a history of work related rhinitis, asthma, or skin symptoms were offered a clinical and immunological investigation including skin prick tests, skin patch tests, and radioallergosorbent tests (RASTs) to detect specific allergy to reactive dyes. Among the 1142 employees, 162 were exposed to reactive dye...

Study of Photooxidative Degradation of Reactive Dyes from Aqueous Solutions by UV/ C102 Process

The color removal of three reactive dyes in an aquatic system without priortreatment was studied. Selected commercial dyes were treated with NaC102 andUV as oxidation agents. Effects of nature of oxidant, temperature, pH ofsolutions, concentration of C107—, contact time of C102— and UV irradiation wereinvestigated. Optimal C102— concentration for color removal in the absence of UVirradiation wa...

Adsorption of the reactive azo dyes onto NH4Cl-induced activated carbon

Background: The efficacy of NH4Cl-induced activated carbon (NAC) was examined in order to adsorb RR198, an azo reactive model dye, from an aqueous solution. Methods: The effects of pH (3 to 10), adsorbent dose (0.1 to 1.2 g/L), dye concentration and contact time on the adsorption efficiency were investigated. Results: The results showed that the removal of dye was highest at a solution pH of ...
