| Abstract: | A. fairly selective and simple fluorescence quenching method for the determination of trace nitrite reacting with Rhodamine 6G in acidic medium to form unfluorescence product was pro-postd. Rhodamine 6G has a maximum excitation wavelength of 350nm and a maxium emission wavelength of 555nm. The calibration graph was rectilinear in range 0- 0.8|ag/mL of nitrite and the detection limt was 0. 008ug/mL. There was no influence of metals ions. The method was applied to pollution water samples with satisfactory reasults. |
