Abstract

A new kind of optical sensor for monitoring dissolved ammonia uses rhodamines immobilized in thin membranes made from ethylcellulose, poly(vinyl chloride) or poly(vinyl acetate). The response to ammonia is the result of a change in the molecular structure of the rhodamine. On exposure to ammonia, the rhodamine is converted to a colorless and non-fluorescent lactone. As a result, fluorescence ...
