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.

Removal of Cadmium from wastewater with plant-derived biosurfactant tea saponin by ion flotation;

Under normal temperature and pressure,a hydrometallurgical process is presented for extracting cobalt,manganese,copper and nickel from earthy cobalt by reduced leaching with SO2-ion flotation-P507 solvent extraction.

The single bubble adsorption model was used to treat the kinetics of cupric ion flotation, and a new method was suggested that the mass transfer coefficients of cupric ion flotation k2 could be caculated by the dynamic surface tension measurement.

An ion floatation—spectrophotometricy method for the determination of trace amounts of iron in industrial recycling water was found.
