Biological treatment, especially enzymatic methods, can be employed for effective and environmental- friendly treatment of dye effluents. Laccase, belonging to the blue multi-copper oxidases category, can oxidize a wide variety of substrates, especially synthetic dyes. In this study, laccase was used to biodegrade two azo dyes, i.e., Direct Red 23 and Acid Blue 92. Before conducting the exp...

The binding of estradiol--receptor complexes of mouse uterine cytosol to oligodeoxynucleotide celluloses is inhibited by the sulfonated polyaromatic dye Cibacron blue F3GA. The dye does not have any effect on the estradiol binding site. Additon of the dye to preformed estradiol--receptor--oligo(dT)-cellulose complex results in the release of estradiol--receptor. The inhibition of binding is com...

Adsorbent prepared from waste plants for the treatment of dyeing effluents have high significance in environmental sustainability. In this research, adsorption of Acid Blue 92AB 92 dye from aqueous solutions on raw and modified diatomite nickel oxide nanoparticles was studied. The effect of different operation parameters such as pH, contact time, initial dye concentration, calcinations and sorb...

vulvar cancer is a rare gynecological malignancy with mainly lymphatic spread. sentinel node mapping plays an important role in the management of this gynecological malignancy. in the current study, we reported our experience in sentinel node mapping of vulvar cancer and review the literature accordingly. since the introduction of sentinel node mapping to the surgical oncology community of our ...

We report the simple synthesis and full investigation of a novel heparin binding dye, mallard blue, an arginine-functionalized thionine. This dye binds heparin in highly competitive media, including water with high levels of competitive electrolyte, buffered aqueous solution and human serum. The dye reports on heparin levels by a significant change in its UV-vis spectroscopic profile. Molecular...

Though an important and chronic source of dyes released to the environment, determination release that occurs during household or industrial washing is usually disregarded. The main scope this study reveal extent dye through washing, understand if modification cotton fabrics with cationic polymers could reduce it. Modified fabrics, dyed Acid Blue 281 (AB) by a mixture reactive Novacron Yellow S...

Highly stable and homogeneously dispersed amino acid coated silver nanoparticles (ANP) of ≈ 10 nm diameter, ranging from 420 to 430 nm are prepared on AgNO3 solution addition to gum of Azadirachta indica solution at 373.15 K. The amino acids were selected based on their polarity. The synthesized nanoparticles were characterized by UV-Vis, FTIR spectroscopy, HR-TEM, XRD, SEM and 1H-NMR. The coat...

In this paper, dye removal ability of the surface modified nanoparticle SMN copper ferrite from single and quaternary systems was investigated. Acid Blue 92 AB92, Direct Green 6 DG6, Direct Red 23 DR23 and Direct Red 80 DR80 were used as model compounds. The effect of surfactant concentration, adsorbent dosage, dye concentration and pH on dye removal was evaluated. The adsorption isotherm and k...

In this research, ZnO nanoparticles (NPs) were synthesized using a binary Zn(II) Schiff-base complex. The complex heat-treated to prepare ZnO nanoparticles via thermal decomposition route at a temperature of 500 °C. The formation of single-phase ZnO nanoparticles and their microstructures were studied by XRD pattern, SEM and TEM observation. The photo-degradation characteristic of the as-prepar...
