It is based on the strong inhibitory effect of manganese(Ⅱ) on the oxidation fading reaction between H2O2 and m-cresol purple in NH3-NH4Cl buffer solution(pH=10.

This paper suggested a m-cresol purple, which could determine quantitatively the content of total acid in vinegar.

A new method for the determination of nitrite was established on the basis of the fact that the decoloration of m-Cresol purple, which was resulted by the oxidation by bromate, was catalyzed by nitite in H_2SO_4 medium.

Spectrophotometric method for determination of content of cationic surfactants in water with bromocresol purple;

Effect comparision of serum albumin determined with bromocresol purple method and bromocresol green method;

The method is based on the cobalt(Ⅱ) catalyzing oxidation of bromocresol purple by hydrogen peroxide in the media of ammonia water using potassium chloride as an activator.

Evaluation of the clinical applicability of bromcresol purple method for measuring serum albumin;

A decatalytic spectrophotometric based on a copper catalyzed redox reaction between potassium peroxydisulfate and bromcresol purple has been developed for the determination of trace copper(Ⅱ) in the percent of sulfuric acid.
