Optimum conditions for the adaptation of the spectrophotometric pyrocatechol violet method for aluminium to a flow-injection system are described. The detection limit is 3 pg Al 1-l and calibration graphs are linear up to 3 or 10 mg 1-l (with 2OOql or lo-r1 injection loops, respectively). The relati
