Description

4,4'-Bis(2-sulfostyryl)biphenyl disodium (BSSPD) is a fluorescent dye that is used to measure the pH of wastewater. BSSPD shows a blue-green fluorescence in acidic solutions and a pink fluorescence in alkaline solutions. It has been shown that the use of BSSPD as an optical probe for wastewater can be used to detect changes in pH levels. This dye is also used to measure the degree of inflammation in the corneal epithelium by measuring the synchronous fluorescence. The effects of hydrochloric acid on BSSPD were studied and validated by optical properties and analytical methods.
