This study was designed to investigate the removal of reactive violet 48 from wastewater using Commercial activated carbon and Coir pith activated carbon. Its adsorption capacity has been tested for the decolourization of waste water containing reactive violet 48. The effect of system variables such as concentration, temperature, contact time and pH were studied. The adsorption data follow Lang...

In this research, at first ordinary Aloe Vera micropowder (OAMP) and its impregnated form (IAMP) as the natural sorbents were prepared and then characterized by several techniques such as Fourier transform spectrophotometry (FT-IR), Scanning electron microscopy (SEM), Elemental analysis (EA), Brunauer–Emmett–Teller and Barrett-Joyner-Halenda (BET/BJH) essay and X-ray powder diffraction (XRD). T...

Sustainable chemistry is a relatively new field that aims to achieve both economic and environmental goals simultaneously. This paper discusses cleaner more sustainable method for dyeing cotton fabric using Direct Violet 09 Reactive 05 dye. It has been noticed good color characteristics were obtained when was dyed with 35 mL of microwave-treated dye solution 7 pH 2 g Aluminum sulfate 30 min at ...

A potential bacterial strain GSM2, capable of degrading an azo dye Reactive Violet 5 as a sole source of carbon, was isolated from textile mill effluent from Solapur, India. The 16S rDNA sequence and phenotypic characteristics indicated an isolated organism as Paracoccus sp. GSM2. This strain exhibited complete decolorization of Reactive Violet 5 (100 mg/L) within 16 h, while maximally it could...

The Pseudomonas aeruginosa GSM3 isolated from dye contaminated soil was able to degrade Reactive Violet 5 completely as a sole source of carbon (300 mgL) within 20 h under static condition. The organism exhibited good decolorization ability in the pH ranges from 5.0 to 9.0 and temperature from 30 to 40C respectively. The optimum degradation was observed at 37C and pH 7. The maximum concentratio...

In this research paper a novel Ultra Violet Photo Catalyst Oxidation (UVPCO) sensor for air and surface sanitization using Common Source (CS) amplifier is presented. The ultra violet photo catalysis is the process in which the highly reactive radicals like H+, OH-and peroxides ions are produced from air in the presence of the ultra violet radiation and photo catalyst. In this process, the free ...

BACKGROUND AND PURPOSE Stroke in preterm and term babies is common and results in significant morbidity. The vulnerability and pathophysiological mechanisms of neonatal cerebral ischemia-reperfusion may differ from those in the mature cerebral nervous system because of the immaturity of many receptor systems and differences in metabolism in neonatal brain. This study details the neuropathologic...

The mutation causing the Silverblue color type (pp) is one of the most used recessive mutations within American mink (Neovison vison) fur farming, since it is involved in some of the popular color types such as Violet and Saphire which originate from a combination of recessive mutations. In the present study, the genomic and mRNA sequences of the melanophilin (MLPH) gene were studied in Violet,...

Since the publication of observations on the selective bactericidal action of gentian violet, 1 studies have been carried on in this laboratory with a large number of other dyes. The technique of divided plates, previously described, has been employed. The results with dyes similar in chemical structure to gentian violet have already been reported. 2 These dyes, like gentian violet, were found ...
