Dye photodegradation using ozone and Nickel ferrite nanoparticle (NFN) as a photocatalyst was studied. The catalyst was synthesized and characterized by FT-IR, SEM and XRD. Textile dyes including Remazol Red RB (RRRB) and Direct Green B (DGB) were degraded as model compounds. Dye degradation was investigated using UV–Vis and ion chromatography (IC) analyses. The effect of catalyst dosage, pH, s...

We examined a simple screening method for judging the complex formation between a drug and aluminum(III) on a spot plate. As few drug had color reaction by basing on the binary complex formation of drug-aluminum(III), the ternary complex formation of drug-aluminum(III)-dye was studied this time using 50 kinds of drugs. The dyes used were Chromazurol S and Erythrosin. As a result, in the drug th...

The research of the present work was to investigate the removal of Rhodamine-B dye from aqueous solution by using Corchorus Olitorius-L Leaves Nano Carbon (ACONC). Generally, dyes are used 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 industry. In this study, Corchorus Olitoriu...

Erythrosine (FD&C Red No. 3) is widely used as a coloring agent for foods, beverages, pharmaceutical preparations, and cosmetics. It has been evaluated for acceptable daily intake by the Joint FAO/WHO Expert Committee on Food Additives (see Annex 1, Ref. Nos. 8, 19 & 35) in 1964, 1969 and 1974. At the 18th Meeting (1974) of the Committee, an ADI of 0 2.5 mg/kg body weight was allocated. Toxicol...

Various synthetic dyes are artificially added to herbal medicines for the purpose of visual attraction. In order monitor illegal usage in medication, a rapid and straightforward analysis method determine is required. The study aimed develop validate high-performance liquid chromatography (HPLC) ten Hawthorn fruit, Cornus Schisandra fruit. Ten such as Tartrazine, Sunset yellow, Metanil Auramine ...

OBJECTIVE To compare mean micro-leakage around 3 types of temporary restorative materials in-vitro, when placed adjacent to permanent restorations (amalgam) in complex endodontic access cavities. STUDY DESIGN Randomized controlled trial. PLACE AND DURATION OF STUDY Dental Clinics, Dental Laboratory and Research Laboratory at The Aga Khan University Hospital, Karachi, from January to June 20...

Decolorization of azo dye Red 3BN by two bacterial species Bacillus cereus and B. megaterium has been analyzed using mineral effluent, consisting of known concentration of the dye in ZZ medium. Physico chemical parameters like carbon source, nitrogen source, temperature, pH and inoculum volume are optimized for the decolorization process by changing one parameter at a time. Optimal condition fo...
