Abstract Background: At present study, acid modified banana leaf ash was used as an adsorbent for the successful removal of Reactive Black 5 (RB5) dye from aqueous environments. Materials and methods: The effect of various operating parameters such as pH of solution, dye concentration, contact time, adsorbent dosage, and the temperature was investigated. Results: Maximum adsorption capacity of ...

Acetylene-black paste without a light scattering layer was applied to meso-porous TiO2 photo-electrode films with a crystalline framework, a low residual carbon, and a tunable morphological pore size. The thermal-treated TiO2 photo-electrode films had an increased acetylene-black concentration with an increase in artificial pores and a decrease in residual carbon. The performance of dye-sensiti...

An isolated fungus, Aspergillus foetidus had the ability to decolourize growth unsupportive medium containing 100 mg L(-1) of reactive black 5 (RB5) dye with >99% efficiency at acidic pH (2-3). Pre-treatment of fungal biomass by autoclaving or exposure to 0.1M sodium hydroxide facilitated more efficient uptake of dye as compared to untreated fungal biomass. Pre-equilibrium biosorption of RB5 dy...

The degradation of an azo dye, Acid Black 1 (AB 1) with ZnO as photocatalyst using natural solar light in aqueous solution has been investigated under different conditions. The degradation is more with solar/ZnO process than with solar/TiO2-P25 process at pH 9. The influence of operational parameters such as the amount of photocatalyst, dye concentration and initial pH on photodegradation by Zn...

BERNSTEIN, M. E. H. M. HOWARD. and G. C. CARROLL. 1973. Fluorescence microscopy of Douglas fir foliage epifloia. Can. J. Microbiol. 19: 1129-1130. Douglas fir needles stained with the fluorescent dye, primulin, were observed microscopically using epiillumination with a mercury arc light source. Microorganisms fell into three categories: algae, which exhibited primary fluorescence; actinomycetes...

Background & Aims of the Study: Discharge of industrial wastewater to the environment has harmful effects. Textile industry is one of the industries that burdens pollutants to the environment. So the wastewater of these industries must be treated before discharging into the environment. Various methods for removing industrial pollutants have been investigated. Among them, AOPs have attracted mu...

Modern real-time PCR systems make it easy to monitor fluorescence while temperature is varied for hundreds of samples in parallel, permitting high-throughput studies. We employed such system to investigate melting transitions of ordered nucleic acid structures into disordered random coils. Fluorescent dye and quencher were attached to oligonucleotides in such a way that changes of fluorescence ...

High oxygen evolution overpotential and inexpensive Ti/Co3O4/PbO2/(SnO2+Sb2O3) and (Ti/(SnO2+Sb2O3) electrodes were investigated in this work. These electrodes were prepared and used as anodes for removal of Reactive Black 5 (RB5) dye in aqueous solution. In some local cases in Palestine, wastewater color was found to be the only problem in meeting local effluent standards. This investigation r...

Lignin degrading white rot fungi, Schizophyllum commune and Lenzites eximia were collected from the living tree of Tramarindus indica and burnt tree respectively from the Western Ghats region of Tamil Nadu, India. The fungi were used for the decolourization of azo dyes such as congored, methylorange, erichrome blackT and also for decolourization of the dye industry effluents. Removal of azo dye...
