Sulfuration flotation is the most widely used technology in malachite beneficiation. However, inhomogeneity of surfaces usually results a non-uniform sulfuration surface. The motivation this work attempt to adopt different functional combination collectors enhance malachite. Accordingly, behaviors and adsorption mechanisms benzohydroxamic acid (BHA) sodium butyl-xanthate (SBX) on surface were s...

zataria multiflora essential oil, hydrogen peroxide(h2o2) and malachite green (mg) were used to assess their effects on rainbow trout egg hatchability and survival of larvae up to 1-1.2 g body weight using spring water at 12.5 °c, dissovled oxygen 8-9 mg/l, carbon dioxide 7±2 mg/l, ammunia

A method is described for counterstaining tissue for use with the glyoxylic acid reaction for visual detection of biogenic amines. Counterstaining is achieved by addition of the fluorescent dye malachite green to the sucrose-phosphate-glyoxylic acid (SPG) solution used for processing of cryostat sections of unfixed tissues. When bound to tissues, the dye provides red-orange fluorescence of back...

We describe a method of determining the distribution function associated with acceptors partaking in Forster resonance ̈ Ž . energy transfer FRET from excited donors. Unlike previous approaches to this problem the method described makes no a priori assumption about the nature of the distribution. The use of an acceptor distribution function in analyte sensing is demonstrated for the first time. ...

The removal of rhodamine B and malachite green from aqueous solutions was studied in batch adsorption systems using Tamarindus Indica fruit shells as sorbents. The well known Freundlich, Langmuir and Redlich-Peterson isotherm equations were applied to the equilibrium sorption data obtained. The sorption dynamics were found to obey the pseudo-second order rate equation and particle diffusions ap...

Malachite green dye is widely used in food and textile industries for various purposes and also used as biocide in the aquaculture industry to control fungal attacks and protozoan infections. Surface and ground water is contaminated by dyes due to discharge of untreated wastewater from industries. The presence of malachite green in water causes serious health effects such as mutagenesis, re...

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.
