Abstract: | This paper presents a convenient determination method for carbaryl in polluted water by micellar-stabilized room temperature phosphorescence with Na(2)SO(3) as oxygen scavenger. The effect of various experimental conditions on the determination of carbaryl is discussed in detail. The analytical curve of carbaryl gives a linear dynamic range of 2 x 10(-7)-6 x 10(-5) mol/l., and a detection limit of 2 x 10(-7) mol/l. A recovery of 90-100% was obtained for 0.05-0.1 ppm carbaryl. |
