Abstract
The gold-solid polymer electrolyte (Au-SPE) sensor for detecting dissolved oxygen (DO) in water was studied. The results indicated that the prepared A u-SPE sensor has a good performance in sensing DO in water. The preparation of electrode was optimized to obtain the best sensitivity. The potential w indows of DO reduction on Au/Nafion(R) electrode in aqueous solutions were determined. The interference of NH4+, NO3- and Cl- were also examined. The Au-SPE sensor shows a high selectivity for DO detection. (C) 2000 Elsevier Science S.A. All rights reserved.
