Reactive dye is a class of highly coloured organic substances, primarily used for tinting textiles. The dyes contain a reactive group, either a haloheterocycle or an activated double bond, which, when applied to a fibre in an alkaline dye bath, forms a chemical bond between the molecule of dye and that of the fibre. The reactive dye therefore becomes a part of the fibre and is much less likely ...

decolorization of aqueous solutions containing ionic dyes (reactive blue 19 and acid black 172) by a tfc commercial polyamide nanofilter (nf) in a spiral wound configuration was studied. the effect of operating parameters including feed concentration (60-180 mg/l), pressure (0.5-1.1 mpa) and ph (6-10) on dye removal efficiency was evaluated. the response surface method (rsm) was utilized for th...

Textile industry effluents contain reactive dyes that may harm our receiving waters. A typical reactive blue (RB) 19 dye is frequently detected in significant concentrations in textile industry effluents. Such dyes have generally shown resistance to decomposition and tend to persist in the environment for long periods and multiply the impacts to water and environment. Therefore, the present inv...

Magnetic Fe3 O4 nanoparticles modified by polypyrrole (PPy@Fe3 O4 MNPs) was synthesized by chemical co-precipitation method and used as an adsorbent for removal of cationic dyes, Reactive Red195, from aqueous solutions. The resulting products are characterized by scanning electron microscope (SEM) and FT-IR. The effects of solution pH value, adsorbent amount, adsorption time and capacity of the...

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. ...

PURPOSE Within the corneal stroma, keratocytes communicate through gap junctions. These plasma membrane channels, which connect the cytoplasm of adjacent cells, are composed of connexins. In a cell culture model, an investigation was conducted to determine whether connexin-based gap junction intercellular communication is present in fibroblasts and myofibroblasts, both of which replace keratocy...

Dye coupling experiments were performed to determine whether the gap junctions connecting Sertoli cells with other Sertoli cells and different germ cell stages in rats showed functional variations. Chop loading of adult rat seminiferous tubules was conducted using fluorescent dextran controls and a variety of low-molecular-weight tracers (lucifer yellow, biotin-X-cadaverine, biotin cadaverine, ...
