Study of pH sensitive membrane based on ion pairs technique
- 化学化工－已发表论文 
A new pH sensitive membrane based on ion pairs technique was developed. Ion pairs indicator, which was formed by bromophenol blue reacting with quaternary ammonium cetyl trimethyl ammonium (CTA) bromide, was homogeneously immobilized on plasticized PVC membrane. The sensitive membrane covers the pH range between 4.0 and 6.0. Preparation, response time, reversibility and reproducibility of the sensitive membrane were investigated. The sensitive membrane was used to determine the effluents in the mixture pool of antibiotic factory.
