In the present work the magnitudes of pigments in the synthetic leather, were measured by means of scanner. Initially synthetic leather samples pigmented by three different pigments of yellow, blue and red colors were prepared. Then the pigmented samples were scanned, and the values of RGB of images were calculated. The artificial neural network (ANN) method used to make relation between RGB va...

in this study, the photocatalytic degradation of methyl orange and congo red dye was investigated inaqueous solution using c,n,s-tridoped sno2 nanoparticles as a nano photocatalyst. the degradationwas carried out under different conditions including the photocatalyst amount, initial concentrationand ph of the solution. the results indicated that the degradation of methyl orange and congo redwas...

BACKGROUND Enzymatic elimination of synthetic dyes, one of the most environmentally hazardous chemicals, has gained a great interest during the two last decades. The present study was performed to evaluate the decolorization and detoxification potential of the purified laccase of Paraconiothyrium variabile in both non-assisted and hydroxybenzotriazole-aided form against six azo dyes. RESULTS ...

The enormous colored effluent discharges due to increased usage of synthetic dyes in textile and other chemical industries pollute both freshwater marine reservoirs cause ecotoxicity serious health problems. This issue needs be addressed skillfully demands an ecofriendly economically feasible technique. Pertaining this, the current study was focused on use a white rot fungus, Resinicium bicolor...

Cell transfection is a technique wherein foreign genetic molecules are delivered into cells. To elucidate distinct responses during cell genetic modification, methods to achieve transfection at the single-cell level are of great value. Herein, we developed an automated micropipette-based quantitative microinjection technology that can deliver precise amounts of materials into cells. The develop...

Abstract Dye is a major source of water pollution. This mini-review highlights the origin dye, its removal strategies, and recent literature methylene blue Congo red adsorption by activated carbons. Adsorption unique process that relies upon physicochemical properties carbon inherent characteristics dye. Also, factors affecting adsorption, such as contact time, temperature, concentration, were ...

Results Materials and Methods Four commercial dyes were used — Remazol® Black BA, Levafix® Blue Ca, Levafix® Yellow CA and Levafix® Red CA (Dystar). A standard anthraquinone dye, Remazol Brilliant Blue R (RBBR, Sigma) was also used. Dye stock solutions were added to solid or liquid decolorization media, up to 200 mg.L-1 final concentration. Rose Bengal Agar and Potato Dextrose Agar (both from D...

Various reactive dyes can elicit occupational asthma in exposed textile industry workers. To date, there has been no report of occupational asthma caused by the red dye Synozol Red-K 3BS (Red-K). Here, we report a 38-year-old male textile worker with occupational asthma and rhinitis induced by inhalation of Red-K. He showed positive responses to Red-K extract on skin-prick testing and serum spe...
