The changes in pH value and in methylene blue capacity,CMB,of 3% bentonite drilling fluid of different salinity in 16 hrs rolling ageing at 150℃ and these characteristics as enfluenced by surfactant added are determined experimentally.

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;

Spectroscopic Study on the Effect of Nanoparticles on the Recognition Interaction of DNA with Methyl Green(MG) and Methyl Blue(MB);

56 NaBH_4-NaOH buffer solution and in the presence of methylene blue(MB),MB was catalysised by Selenium(Ⅳ)to oxidize S~(2-) fade ultraviolet photometric and to determine the content of Se.

In this thesis,two novel composites of TiO_2:doping catalyst and magnetic photocatalyst were successfully designed and prepared with altering property to TiO_2,Their catalytic activities were evaluated by measuring the decolorization efficiency of MB in aqueous solution.

TiO_2/SiO_2 aerogels are produced through sol-gel process followed by non-supercritical drying with the structure of their samples characterized,and photocatalytic activity of the resultant aerogels for degradation of methylene blue (MB) is also studied.

In this paper, effects of hydrogen peroxide and Cl~-/Br~-/I~- on the photochemical degradation of methylene blue (MB) are studied by static method.
