Photoinitiator-free Photo-reactive Coloration of Wool Fabrics Using C.I. Reactive Black 5

removal of reactive black 5 from aqueouse solutionusing catalytic

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...

Dyeing of Indian wool with reactive dyes

Wool fibres have been chemically modified by reduction I chlorination under acidic pH Ipre-swelling in conc. formic acid prior to their dyeing with indigenous reactive dyes of different molecular configurations to enhance the reactive dye uptake on wool fibre substrate. The pretreatment processes are inexpensive, less harmful and less time consuming as against the use of imported special wool r...

Adsorption Behaviour of Reactive Black Dye 5 by Magnetically Separable Nano-adsorbent

Dyes in the textile industry are the most significant source of pollutants, which cause damaging effects to people’s health. Reactive black 5 (RD5) is an anionic color that is currently used in the textile industry. This study is designed to provide the strategies to synthesize and characterize the new family of functionalized magnetite nanoparticles via a chemical co-precipitation method with ...

Photo-reactive polyvinylalcohol for photo-immobilized microarray.

A new photo-reactive polymer, polyvinylalcohol modified with phenylazido groups, was synthesized as a microarray matrix. The polymer is soluble in water and spin-coated onto glass plate. Aqueous solutions of proteins were micro-spotted onto the coated glass and were fixed by ultraviolet light irradiation. Subsequently, cell adhesion on the photo-immobilized protein microarray was investigated. ...
