抄録

A new ammonia optical sensor was designed using bis(acetylacetoneethylendiamine)tributylphosphin cobalt(III) tetraphenylborate complex, coated on transparent triacetylcellulose film as membrane. The change in the absorbance of the optode at the maximum wavelength of 408 nm was related to ammonia concentration in aqueous samples. A buffer solution with a pH of 9 (sodium borate-HCl) was used. The optode was fully regenerated in pH 2. The linear dynamic range for determination of ammonia was 3.3 × 10<sup>-4</sup> to 6.9 × 10<sup>-3</sup> mol l<sup>-1</sup> with a detection limit of 5.0 × 10<sup>-5</sup> mol l<sup>-1</sup> and a response time range of 4 - 6 min. This membrane was successfully applied for determination of ammonia in drinking water.
