Recently, the research on remediation of aqueous organic pollutants over visible-light-active photocatalysts has got much attention. Therefore, this study reports fabrication Co3O4-Bi2O3 heterojunction photocatalyst for photodegradation rhodamine B dye. The was synthesized by coprecipitation method and characterized XRD, EDS, SEM, TEM, TGA, FTIR. as-prepared utilized as a abatement It observed ...

1. The amounts of iodine in nationally representative samples of prepared and cooked groups of foods and in a wide variety of individual foods and food products were determined colorimetrically. The amounts of erythrosine, a red food colour containing 577 mg I/g were also determined in selected foods and diets by high-performance liquid chromatography. 2. The average British diet was calculated...

FD&C Red No.3 (erythrosine) has been used as a dye in foods, drugs and cosmetics since its approval by the US Department of Agriculture in 1907. In 1977 the Certified Color Manufacturers' Association (CCMA) initiated studies on FD&C Red No.3 including chronic toxicity and carcinogenicity studies in rats and mice. Data from the CCMA chronic studies revealed an increased incidence of thyroid foll...

The possibility of removing certain pharmaceuticals from wastewater was tested using Octolig, a commercially available material with polyethyldiamine moieties covalently attached to high-surface area silica gel. Selected drugs and drug models were subjected to column chromatography for removal by means of ion encapsulation, the effectiveness of which would depend upon having appropriate anioni...

The spectral (both absorption and fluorescence) and photoelectrochemical studies of some anionic xanthene dyes namely erythrosine B, rose bengal and eosin have been carried out in micellar solution of cationic cetyl trimethyl ammonium bromide (CTAB), anionic sodium dodecyl sulphate (SDS) and neutral triton X-100 (TX-100). The results show that all these dyes form 1:1 electron-donor-acceptor (ED...

The ability of the activated carbon prepared from Eichornia Crassipes to remove Reactive Magenta B and Reactive Turquoise Blue dyes from aqueous solution has been carried out as a function of contact time, dose (0.1-0.60 mg/50ml for Magenta B and 0.25-2.0 mg/50ml for Turquoise Blue), pH (2-10) and concentration (25, 50, 75, 100mg.L). An amount of 0.6 g of the adsorbent could remove 56.0% of the...

introduction: this study compared apical dye penetration using lateral condensation technique (lc) and lc technique with a reciprocal handpiece (mechanical lateral condensation or mlc) as a new method. materials and methods: forty-eight human extracted straight canine teeth were used. after crown amputation, the teeth were randomly divided into four experimental groups of 10 teeth each and two ...

The research of the present work was to investigate the removal of Rhodamine B dyes from aqueous solution by using Activated Acacia Nilotica Shell Carbon (ANSC). Generally, dyes are organic compounds used as colouring products in chemical, textile, paper, printing, leather, plastics and various food industries. The need for the treatment of dye contaminated waste water passed out from the indus...

The interaction of crythrosine B (ErB), a commonly used dye for coloring foods and drinks, with bovine scrum albumin (BSA) was investigated both in the absence and presence of bilirubin (BR) using absorption and absorption difference spectroscopy. ErB binding to BSA was reflected from a significant red shift of 11 nm in the absorption maximum of ErB (527 nm) with the change in absorbance at lam...
