Zirconium-2,6-naphthalenedicarboxylate metal-organic framework (Zr-NDC MOF) was prepared using ultrasound-assisted synthesis and tested for the adsorptive removal of crystal violet (CV) dye from aqueous solution. The pristine Zr-NDC characterized powder X-ray diffraction, scanning electron microscopy, thermogravimetric analysis, energy-dispersive spectroscopy, Fourier-transform infrared, elemen...

In this study, an alternative precursor for production of biomass-derived activated carbon was introduced using dragon fruit (Hylocereus costaricensis) peels. Chemical activators such as FeCl3, MgCl2, ZnCl2 were used in the thermal carbonization process to convert into porous (PC). However, heteroatom-doped PC catalysts including N-, B-, and P-doped field dye removal is highly desirable. Severa...

Abstract In the current work, we demonstrate a design to act as Gamma-ray radiation dosimeter based on one-dimensional photonic crystal (1D-PhC). The basic concept of present is Porous Silicon (PSi) infiltrated by poly-vinyl alcohol (PVA)-polymer doped with violet (CV) and carbol-fuchsine (CF) dyes. mechanism suggested shift bandgap (PBG) higher wavelengths exposed gamma-ray doses from 0 70 Gra...

This work is reported on the synthesis of Fe3O4/eggshell nanocomposites in the absence of anystabilizer or surfactant. Fe3O4 magnetic nanoparticles were established on the egg shell. The adsorptionof Malachite green (MG) and Crystal violet (CV) as cationic dyes and Eriochrome Black T (EBT) as ananionic dye by magnetite nanoparticles loaded egg shell (MNLES) and magnetite nanop...

Sodium azide-crystal violet-agar and a modified blood-azide (MBA)-agar were used to isolate Erysipelothrix rhusiopathiae from swine tissues. There was no significant difference in the number of isolations. However, 78% of the isolants from modified blood-azide medium required only 24 hr of incubation, whereas all of the isolants obtained on sodium azide-crystal violet medium required 48 hr.

In this report, we propose a novel starch-mediated photochemical reduction method for synthesizing micrometer-sized gold nanoplates and the possibility of using them as a tip-enhanced Raman scattering (TERS) substrate. To reduce gold ions, a starch chain firstly forms a complex with AuCl(4)(-), and the gold ion is subsequently reduced by receiving an electron from a chloride ion and generating ...

Purification of dye-laden water endures to be immensely challenging owing the occurrence highly persistent and non-biodegrade dyes, which pose a potential threat humans, flora, fauna, environment. The environmental problem was addressed by facile fabrication poly [(2-acrylamido-2-methyl-1-propane sulfonic acid-co-acrylamide-co-acrylic acid)] hydrogels cross-linked via sodium borate (SB), graphe...

The removal of crystal violet from aqueous solution by NiFe2O4 magnetic nanoparticles treated with sodium dodecyl sulfate was investigated. The modified magnetic nanoparticles were prepared by chemical reaction of a mixture of Ni+2 and Fe+3 ions mixture in aqueous solution at the presence of ammonia and then sodium dodecyl sulfate was utilized as an ionic surfactant to modified the obtained mag...

The present study was aimed to green synthesize of α-Fe2O3 nanoparticles (NPs) using flower extract Musa acuminata and examination their antibacterial photocatalytic activities. synthesized NPs were investigated UV-visible spectroscopy, which exhibited a colour change pattern, the maximum absorption peak at 265 nm confirmed formation NPs. FTIR analysis showed presen...

Abstract This study identified a common Streptomyces sp. (MN262194) from forest soil as an efficient decolorizer of triphenylmethane (TPM) dyes. Partial 16S rRNA sequencing the isolate possibly bacillaris (similarity 99.32%). Live and dead cells were applied to decolorize Malachite Green (MG), Methyl Violet (MV), Crystal (CV), Cotton Blue (CB). The decolorization efficacy for both cell types wa...
