A Preliminary Note on the Decolourisation of a Solution of Methylene Blue When Left in Contact with Kala-Azar Serum
نویسندگان
چکیده
Recently while experimenting with solutions of various dye stuffs on kala-azar serum, we observed that when solutions of methylene blue were left in contact with kala-azar serum, the dye gradually decolourised. We have tried out various strengths of methylene blue solutions varying from 1 in 2,000 to 1 in 80,000 and obtained the most satisfactory results when working with a solution of 1 in 40,000. The procedure adopted was to take 0.5 cc. of

Decolorization of Methylene Blue from Aqueous Solution Using Ultrasonic / Fenton Like Process (RESEARCH NOTE)
Docolorization of Methylene Blue was investigating using a Ultrasonic/Fenton like reactor in batch mode. The effects of pH, reaction time, initial concentration of dye, H2O2 and Fe on the dye removal was studied. It was found that the increase of initial dye and H2O2 concentration and the increase of initial pH, are not beneficial for improving the dye removal efficiency. Increasing the dye con...
متن کاملRemoval of methylene blue dye aqueous solution using photocatalysis
The nano sized TiO2 and ZnO are the most active photocatalysts. Methylene blue was used as a reference molecule for the photocatalytic degradation. The TiO2 and ZnO can totally remove methylene blue dye. The effect of various process parameters like initial concentration, contact time, dose of catalyst and pH on the extent of removal of dye by photocatalysis in presence o...

متن کاملDye Adsorption on the Blends of Saffron Petals Powder with Activated Carbon: Response Surface Methodology
One of the famous dyes is methylene blue (MB) which is a symbol of hazardous dyes. In this research, methylene blue was adsorbed using the blends of saffron petals with activated carbon. Five independent variables involving pH (2-13), contact time (5-270 min), saffron petals powder dosage (0.1-10 g/l), initial concentration of methylene blue solution (20-300 ppm) and activated carbon dosage (0....
متن کاملInvestigation of performance of bimodal/functionalized mesoprorous silica nanoparticles on the adsorption of methylene blue from aqueous solution
In this study, bimodal mesoporous silica, i.e. UVM-7, was synthesized and functionalized withsulfonic acid and characterized using XRD, nitrogen physisorption, SEM, TEM and acid/basetitration. The results displayed that bimodal mesopore structure was firmly formed and acidicfunctional groups were grafted on the surface of the UVM-7. The concentration of the acidicfunctional groups was determine...
