Expanded graphite nanosheets (EG-nanosheets) were used for adsorption of Malachite Green (MG) from aqueous solution. The influences of dye concentrations, absorbent dosage, pH values and the temperatures on the adsorption were investigated as well. The dye adsorption experiments were carried out by utilizing batch procedure. EG-nanosheets were initially characterized by scanning electron micros...

Live cell imaging requires bright photostable dyes that can target intracellular organelles and proteins with high specificity in a no-wash protocol. Organic dyes possess the desired photochemical properties and can be covalently linked to various protein tags. The currently available fluorogenic dyes are in the green/yellow range where there is high cellular autofluorescence and the near-infra...

Statistical designs were applied for optimizing laccase production from a white-rot fungus, Ganoderma sp. rckk-02 under solid-state fermentation (SSF). Compared to unoptimized conditions [2,154 U/gds (Unit per gram of dry substrate)], the optimization process resulted in a 17.3-fold increase in laccase production (37,423 U/gds). The laccase produced was evaluated for its potential to decolorize...

Research work reports the synthesis method of nanocomposite ZnO/CuO/β-CD and it is characterized by X-ray diffraction UV-vis absorption spectra. Photocatalytic activity measured using organic dye Malachite Green (MG) as model pollutant. Dye degradation follow pseudo first order kinetics. Efficiency photocatalytic process percentage degradation. Rate constant band gap also calculated.

Mycobacteria can tolerate relatively high concentrations of triphenylmethane dyes such as malachite green and methyl violet. To identify mycobacterial genes involved in the decolorization of malachite green, a transposon mutant library of Mycobacterium smegmatis mc2 155 was screened for mutants unable to decolorize this dye. One of the genes identified was MSMEG_5126, an orthologue of Mycobacte...

In the present study, a Cameroonian smectite was used as an adsorbent to model adsorption kinetics of three textile dyes (malachite green, methyl red and acid blue 74) from aqueous solution in batch system. The effects pH temperature were evaluated on capacities, times required reach equilibrium mechanisms involved. It can be seen that, although are independent medium, process studied is favour...

The organic dyes directly pollute the soil, water, plants and all living systems in the environment. In the present investigation, adsorption of brilliant green dye on silica from aqueous solution was studied. The dye adsorption mechanism was studied on the basic surface of silica. The adsorption parameters were optimized to maximum adsorption. The adsorption mechanism of brilliant green on sil...

A facile method of solution combustion was used to synthesize a new solid solution Bi(2)Ce(2)O(7). The structure was determined from powder X-ray diffraction (PXRD) and found to crystallize in the space group Fm3m with cell parameter a = 5.46936(9) Å. The particle sizes varied from 5 to 6 nm. The degradation of cationic dye malachite green (MG) was investigated under solar radiation as the band...

Present study was performed to investigate the variables that influence the removal efficiency of malachite green (aniline) dye from aqueous solution by an electrochemical (EC) technique. The batch EC studies were performed using iron electrode to evaluate the effect of operating parameters such as pHo and processes parameters such as current density and initial dye concentration. Parameters pH...
