摘　　要：研究了溶剂浮选光度法测定水中活性艳红X-3B时的影响因素，并优化了溶剂浮选条件。实验表明，本法的浮选率大于96％，当染料舍量在50～2500μg／50mL范围时与离子缔合物的吸光度具有很好的线性关系，相关系数为0．9998，RSD为1．4％。该法与溶剂萃取法相比，分离富集效果更好，并已成功用于实际印染废水中活性艳红X-3B的测定。A novel method for the determination of reactive brilliant X-3B using solvent flotation spectrophotometric method has been developed. The effect of various experimental parameters for solvent flotation （catching reagent, pH, time, flotation solvent and ionic strength, etc. ） were discussed. Linear ranges were found to be 50～2 500 μg/50mL,with the square of the correlation coefficient （r^2）= 0. 9998. Relative standard deviation （n=6） was found to be 1.4% for 10 mg/L. Compared with solvent extraction, this method has better concentration effect. The proposed method has been successfully applied to the determination of reactive brilliant X-3B in dye waste water.
