It was based on the principle of methylene blue spectrophotometric method.

Study on photocatalytic degradation for soluble methylene blue in water by SO_4~(2-) modified nano-sized TiO_2;

Anodic stripping voltammetric determination of Sn(II) at poly methylene blue/multiwalled carbon nanotube modified electrode;

Kinetic analysis and mechanisms for adsorption of methylene blue from aqueous solution onto δ-MnO_2;

Adsorption behavior of copper ion and methylene blue on citric acid-esterified wheat straw;

Preparation and utilization of rice straw cationic sorbent bearing carboxyl groups for removal of methylene blue from aqueous solution;

Measurate Trace Copper by Catalyze Dyn ——Cu(II)—Methylene blue—H_2O_2;

Decoloration of methylene blue by ceramisrt packed-bed in pulsed high voltage electric field;

Preparation of TiO_2/exfoliated-graphite composite and photocatalytic degradation of methylene blue;

The absorption dynamics of methylene blue in alga and its effect on active oxygen;

The protonated coke waste was used as a new type of biosorbent for the removal of anionic dye Reactive Red 4(RR4) and cationic dye Methylene Blue(MB).

Their photocatalytic properties are investigated by examining the degradation of methylene blue.

The detoxifying test of rabbit nitrite poisoning with large dosage Methylene blueand Vitamine C was made,and achieved ideal detoxifying results.

FT-IR absorption characteristics and average molecular parameters of the mixtures were correlated;the molecular parameters included the number ratio of methylene to methyl(NCH2/NCH3),hydrogen aromaticity(faH),atomic ratio of hydrog.

It is found that there exists a linear relation between the ratio of absorptivity of IR in 1460 cm-1 band to that in 1380 cm- 1 band and the ratio of methylene to methyl groups in the mixtures.

The oxidation of methylene is an important part.
