Activated carbon derived from Ficus Binjamina agro-waste synthesized by pyro carbonic acid microwave method and treated with silicon oxide (SiO2) was used to enhance the adsorption capability of malachite green (MG) dye. Three factors concentration dye, time mixing, amount activated four levels were investigate their effect on MG removal efficiency. The results show that 0.4 g/L dosage, 80 mg/L...

A bacteria strain Bacillus thuringiensis RUN1identifiedby 16s RNA gene phylogenetic analysiswas used to decolorize malachite green, a triphenylmethane dye in simulated wastewater. The ability of the organism produce extracellular laccase and degrade were also investigated. Results showed that decolorized (84.67 ± 1.19 %) green at 40 mgl-1 within 6 h; decolorization was associated production by ...

In the present study, new emerging 2D Mxene nanosheets (MXNSs) were synthesized from MAX phase powders of Ti3AlC2 and then characterized using a scanning electron microscope (SEM) X-ray diffraction (XRD) to explore chemical physical properties prepared MXNS. The characterization MXNS indicated formation exfoliated MXene (Ti3C2) as result HF treatment phase, which was confirmed by XRD measuremen...

This paper presents the feasibility of removal of basic dye malachite green from aqueous solutions by using a low cost AC-MnO2-NC. Batch adsorption experiments were carried out as a function of pH, contact time, initial concentration of the adsorbate, adsorbent dosage and temperature . Langmuir, Freundlich and Tempkin isotherms were also studied . Pseudo first order, Pseudo second order , intra...

Wavelength-tunable pulses from a synchronously pumped cavity-dumped dye laser were compressed by using an optical fiber. The resulting 250-fs pulses were used to study ground-state recovery in malachite green solutions. The coherent coupling artifact was removed from the data by an antisymmetrizing procedure, and the resultant signals were deconvoluted in the usual manner. The ground-state reco...

A simple and highly sensitive method is proposed for determination of trace amount of cerium. New method involves bleaching of greenish colour dye-malachite green, by the action of iodine, which is released by reaction between potassium iodide and cerium (IV) in acidic medium. Beer’s law is obeyed over concentration range of 0.6 to 4.6 μg cerium (IV) in final volume of 25 ml (0.024-0.184 ppm). ...

Background & objectives: Malachite green color has been extensively used in aquaculture industry around the world. The drainage of colored wastewater containing malachite green to aquatic ecosystems has created very serious risks for human health and the environment. The purpose of this study was to investigate the removal of green malachite from aqueous solutions using photocatalysis of titani...

Exposure to malachite green (MG) may pose great health risks to humans; thus, it is of prime importance to develop fast and robust methods to quantitatively screen the presence of malachite green in water. Herein the application of extractive electrospray ionization mass spectrometry (EESI-MS) has been extended to the trace detection of MG within lake water and aquiculture water, due to the int...
