摘要：

A spectrofluorimetric sensor for the determination of beryllium based on the use of morin, immobilized in a resin exchanger located in a flow cell, is proposed. The determinative method developed with this sensor has a linear range between 1 and 40 ppb, with a relative standard deviation of 1.71% and a sampling frequency of 30 h-1. Its selectivity allows the determination of beryllium in simulated alloy samples with excellent results.
