| 英文摘要 | a novel small-volume fiber-optic evanescent-wave absorption sensor based on the griess-ilosvay reaction has been developed and evaluated for nitrite determination. the sensor was constructed by inserting a decladded optical fiber into a transparent capillary to form an annular column microchannel. the evanescent wave (ew) field produced on the optical fiber core surface penetrated into the surrounding medium and interacted with the azo dye, which was generated by the reaction of nitrite and nitrite-sensitive reagents. the detector was designed to be parallel to the axis of the optical fiber. the defined absorbance was linear with the concentration of nitrite in the range from 0.05 to 10 mg l(-1), and the detection limit was 0.02 mg l(-1) (3 sigma) with the relative standard deviation (rsd) of 2.6% (n=8). the present sensor was successfully used to determine nitrite in real samples of mineral water, tap water, rain water, and seawater. the results were consistent with the data obtained by standard spectrophotometric method, showing potential of the proposed sensor for practical application. |
