Abstract The use of ionic flocculation is proposed to remove malachite green (MG), in this case, from water. A surfactant with the polluted solution and calcium added. surfactant-calcium reaction forms a precipitate, which aggregates into flocs on agitation. adsorb MG, can then be removed by centrifugation. Ionic was assessed varying parameters including: MG concentrations, electrolyte content,...

A new approach to structural sensing, fluorescence resonance energy transfer nanotomography, which interprets fluorescence decay measurement in terms of site density analysis of molecular distributions, has been applied to a glucose sensor based on competitive binding with malachite green labelled dextran to the sugar binding protein concanavalin A labelled with allophycocyanin. Opportunities f...

Enzymes Immobilization onto different types of the substrate could be helpful in various applicationsof biomedical devices and biosensors. Enzyme activity and stability could be affected by support andmethod of immobilization. In this study, the silver metal foam was successfully synthesized by thesoft-shell method and then was coated with silica. Then, glucose oxidase (GOx) immobilized on nonc...

background: the use of chemical materials such as malachite green to disinfect fish eggs is banned in many countries due to its reversed environmental effects. objectives: the purpose of this study was to investigate the effect of metalonic sumac extract as antifungal agent on eggs of schizothorax zarudnyi during the incubation period and to compare its effects with malachite green. methods: 24...

graphene, a new member of the carbon family, was used as an adsorbent due to its exceptional capability to remove rhodamine b (rb) and malachite green (mg), two organic dyes, from aqueous solutions. adsorption kinetics of rb and mg onto graphene and adsorption capacity of the adsorbent were studied. also the effects of parameters, including ph, contact time, temperature, and adsorbent dosage we...

EXAFS measurements in the corrosion deposits were performed on Bell Labs-UIUC beamline X16C at the NSLS at Brookhaven National Laboratory in grazing incidence fluorescence mode at room temperature. EXAFS in the reference Cu and Pb metal foils, malachite, cerussite and hydrocerussite were measured in transmission. Sagittally focused second crystal in the double crystal Si (111) monochromator all...

The purpose of the present study was to evaluate and assess the capability of Zataria multiflora, Geranium herbarium, and Eucalyptus camaldolensis essential oils in treating Saprolegnia parasitica-infected rainbow (Oncorhynchus mykiss) trout eggs. A total of 150 infected eggs were collected and plated on glucose-pepton agar at 24°C for 2 weeks. The antifungal assay of essential oils against S. ...
