How do you degrade methylene blue?

How do you degrade methylene blue?

Photocatalytic oxidation is considered to be one of the most effective ways of degrading methylene blue. A number of catalysts have been reported for methylene blue (MB) degradation over the past decade.

What is the structure of methylene blue?

Methylene blue/Formula

What wavelength does methylene blue absorb?

around 664 nm
Methylene blue aqueous solution absorbs light of around 664 nm, and shows bright blue.

How do you calculate percentage of degradation dye?

To know the percentage of dye degradation; First, have the data of the initial dye concentration before its action, D0 (time=0 hrs). Then, find the dye concentration reduced during its action at a particular time, Dt (say, t= 2hrs).

Is methylene blue basophilic or eosinophilic?

Methylene blue is a cationic dye. It binds to tissue anions and stains basophilic substances, including nucleic acids. Eosin is an anionic dye and is attracted to positively charged protein groups (cations), such as amino groups. It is an acidophilic stain.

What biological molecule does methylene blue stain?

Biological staining Since it is a temporary staining technique, methylene blue can also be used to examine RNA or DNA under the microscope or in a gel: as an example, a solution of methylene blue can be used to stain RNA on hybridization membranes in northern blotting to verify the amount of nucleic acid present.

What is the type of photocatalyst?

The most commonly used homogeneous photocatalysts include ozone and photo-Fenton systems (Fe+ and Fe+/H2O2). The reactive species is the •OH which is used for different purposes. The mechanism of hydroxyl radical production by ozone can follow two paths.

How does a photocatalyst work?

Photocatalysis is a process in which light energy is used to drive pairs of chemical reactions. Due to their activated state, the electron and hole perform chemical reduction and oxidation as though they were highly reactive reagents in a chemical reaction.
