Ammonia detection in water using balloon-like fiber optic sensor coated with oxazine and PDMS

This paper presents the detection of ammonia in water using a balloon-like fiber optic sensor coated with Oxazine 170 perchlorate and polydimethylsiloxane (PDMS). The sensor was prepared by removing a middle portion of a plastic optical fiber cladding using acetone. The uncladded fiber optic sensor...
