摘要
以桑色素作显色剂，采用流动注射分光光度法测定水中铝的含量。在桑色素质量浓度为0．8g／L、聚氧乙烯辛基苯基醚体积分数为1．0％、进样环体积为400μL、检测波长420nm的条件下，采用流动注射分光光度法对水中铝的含量进行测定，本方法的线性范围为2～300μg／L，检出限（信噪比为3）为0．124μg／L，相对标准偏差为2．9％，加标回收率为96．4％～101．8％。
The content of aluminum in water was determined by the flow injection spectrophotometry using morin as chromogenic reagent. When the mass concentration of morin is 0.8 g/L, the volume fraction of polyoxyethylene octyl phenyl ether is 1. 0% , the sample volume is 400 μL and the detection wavelength is 420 nm, the linear range for the method is 2 -300 μg/ L, the detection limit （signal-to-noise ratio is 3） is 0. 124μg/ L, the relative standard deviation is 2.9% and the recovery rate is 96.4 - 101.8%.
