backgroud and purpose: dye is one of the problems of industrial effluent such as textile industries. the dyes can be removed by various methods. therefore, the aim of this study was the evaluation of adsorption rate of reactive red 198 from aqueous solution by activated red mud. materials and methods: this research was a lab study. activated red mud was used as an adsorbent to remove reactive r...

Yeast hexokinase, a homodimer (100 kDa), is an important enzyme in the glycolytic pathway. Although Cibacron Blue 3G-A (Reactive Blue 2) has been previously shown to inactivate yeast hexokinase, no comprehensive study exists concerning the nature of interaction(s) between hexokinase and the blue dye. A comparison of the computer-generated three-dimensional (3D) representations showed considerab...

in the present work, a new kind of alumina-based adsorbent with high selectivity and stability and efficient adsorption was prepared. alumina was coated with an oxazolone azo dye, 2-(4-{2-[4-(dimethylamino) phenyl]-1-diazenyl}phenyl)-4-[1-phenyl methylidene]-5(4h)-oxazolone, and then used for preconcentration of trace amounts of palladium. the analytical procedure involved the complex formation...

background: the presence of even a very small quantity of dye in water bodies is undesirable and affects the water bodies. dye removal from industrial waste water is significant; hence in this study, a material that is an economical waste product was employed to test its acid dye removing capacity from aqueous solution. methods: in this study, batch mode experiments were performed in the sorpti...

in this study, a functional colorant, berberine, extracted from berberis vulgaris wood was applied onto wool fiber using the extract of roots of rumex hymenosepolus as biomordant. the effect of treatment variables on the color strength of dyed fibers was examined. the fastness properties of dyed wool against washing, light, dry and wet rubbing were evaluated. dyed samples were tested for antiba...

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 ...
