✦ Synopsis

The development and optimization of a fluorimetric reaction-rate method for the determination of aluminum is described. The rate of formation of the fluorescent aluminum chelate of 2,4,2'trihydroxyazobenxene-5'-sulfonic acid is measured within 24 s after mixing with one reagent solution. The technique exhibits a detection limit of 0.1 ng ml-' and a linear dynamic range of over four orders of magnitude. The technique was successfully applied to the determination of aluminum in NBS spinach leaves and a sample of river water.
