Bi2Fe4O9 crystalline ceramic was successfully synthesized through a soft chemical route at lower sintering temperature for analysis of photocatalytic behavior with respect to adsorption Congo Red (CR) in the presence UV-VIS irradiation. The single-phase formation confirmed by powder X-ray diffraction studies and particle size observed TEM found be 148 ± 5 nm which reveals nature materials. Addi...

Copper oxide (CuO) nanoparticles (NPs) were decorated on reduced graphene (rGO) through the effective synthetic route method. Powder X-ray diffraction, Fourier transform infrared, ultraviolet-visible absorption, and scanning electron microscopy techniques used to analyze chemical structure, functional groups, absorbance, morphology. Under visible light illumination, CuO/rGO nanocomposites have ...

Abstract Size-controlled Pb0.06Fe0.7O3 nanoparticles (Pb-FeONPs) were fabricated by the thermal co-precipitation method and characterized FE-SEM, EDX, XRD, IR techniques. The SEM XRD images showed average size distribution crystallite of 19.21 nm 4.9 nm, respectively. kinetic model Congo Red (CR) adsorption onto Pb-FeONPs was verified found to be a pseudo-second-order reaction. Langmuir plot be...

Most of the dyes are carcinogenic and mutagenic in nature. Plants potential candidates to remediate textile dye wastewater from contaminated sites. The present study aimed design an efficient hydroponic system screen ornamental plant species for removal synthetic solution triarylmethane Methylene Blue (MB) diazo Congo Red (CR). plants selected screening Trachyspermum ammi, Tagetes erecta, Hibis...

Most dyes related to trypan blue inhibited hemolytic activity of oligonucleotide-streptolysin S (SLS) complex, an exotoxin produced by Streptococcus pyogenes. Order of the inhibition was: trypan blue greater than benzo blue 2B greater than Congo red greater than Evans blue greater than benzo purpurine 4B greater than thiazine red greater than trypan red. When resting streptococcal cells were in...

tio2 /fe3o4 nanocomposites with various tio2:fe3o4 ratios were synthesized by an ultrasonic-assisted deposition-precipitation method and their uv-light decolorization of congo dye and magnetic separation were investigated. the nanocomposite samples were characterized by scanning electron microscopy (sem), powder x-ray diffraction (xrd), surface area analayzer (bet) and fourier transform infrare...

releasing of textile dye effluents into general water bodies is a major environmental and healthproblem. color removal, in particular, has recently become of major scientific interest, as indicated by themultitude of related research reports. during the past two decades, several physico-chemical decolorizationtechniques have been reported, few, however, have been accepted by the textile industr...

Micellar structures formed by self-assembling Congo red molecules bind to proteins penetrating into function-related unstable packing areas. Here, we have used Congo red--a supramolecular protein ligand--to investigate how the intramolecular structural changes that take place in antibodies following antigen binding lead to complement activation. According to our findings, Congo red binding sign...

Supramolecular micellar structures have been proposed as carriers in aim-oriented drug transportation to a target marked by specific immune complexes. In this study, the self-assembling dye Congo red was used as a model supramolecular carrier and its accumulation in the target was studied in vivo. The target was created in vivo as the local specific inflammation provoked by subcutaneous injecti...

Thermodynamic properties of complexes of Congo Red (CR) dye with amyloid  (A) peptides were studied by both absorption spectroscopy and isothermal titration calorimetry (ITC). Based on the absorption spectrum for the formation of CR-Aβ complexes in phosphate buffered saline solution (pH 7.4), van’t Hoff plots over a temperature range of 10oC to 70oC were created for CR-Aβ1-40, -Aβ12-28, and -...
