摘要：

Boron can be determined spectrofluorimetrically based on the reaction of borate ion and Alizarin Red S in aqueous media using flow-injection analysis. The carrier stream was deionized water and the reagent streams were 1% (w/v) EDTA, phosphate buffer (pH 7.5) and 2 x 10(-3) M Alizarin Red S solutions. The injection rate was 50 h(-1). The calibration graph was linear up to 40 mu g ml(-1) boron and the relative standard deviation for the determination of 4.0 mu g ml(-1) of boron was 0.83% (n = 10). The detection limit was 0.34 mu g ml(-1) based on injection volumes of 250 mu l. The system was applied to the determination of boron in electroplating solutions.
