Study on spectrophotometric determination of trace amount of bromate by oxidative decoloration of toluidine blue;

Determination of Ascorbic Acid in Pharmaceutical Products with Toluidine Blue by Kinetic Spectrophotometry;

Study of the effect of toluidine blue(TB)-mediated photodynamic inactivation to the periodontal pathogens from supragingival plaques;

A strain WZR-B was domesticated,screened and isolated from a contaminative river,which can utilize aniline blue as the sole carbon and energy source for growth.

Based on the fluorescent property of specific integration of aniline blue dye and standard functional yeast β-1,3/1,6-glucan, some influencing factors of glucan fluorometry were investigated and β-glucan fluorescent determination method was developed.

The method is based on the catalytic effect of Mo(Ⅵ) on the reduction of aniline blue water soluble with hydrazine dihydrochloride,The effect of the solution pH, the reagent concentration and interfering ions on reaction have been discussed.

Spectrophotometry and applications of netilmicin with pontamine sky blue;

RESULTS In the acid condition,congo red(COR) and evans blue(EVB) and pontamine sky blue(POB) reacts with micronomicin(MINC) to form red or blue ion association complexes.

Under acidic condition,spectinomycin(SPM) was reacted with acid chrome blue K(ACBK),evans blue(EVB) or pontamine sky blue(POB) to form red or blue ion association complexes showing obvious fading peaks.
