| Abstract | A highly sensitive fluorescence quenching method for the determination of silicate based on the formation of an ion associate between molybdosilicate and Rhodamine B (RB) in nitric acid medium was developed. A flow injection system coupled with a fluorescence detector was used for the measurement of fluorescence intensity at 560 and 580 nm as excitation and emission wavelengths, respectively. The calibration graph for Si showed a linear range of 0.1-5 ng cm(-3) with correlation coefficient of 0.9999, and the detection limit of 0.06 ng cm(-3). The proposed method was successfully applied to the determination of silicate in ultrapurified water with satisfactory results. |
