A flow-injection spectrophotometric method for the determination of orthophosphate is described. The signal from the yellow phosphovanadomolybdic acid complex is recorded at 400 nm. The detection limit is 0.1 mg P 1-l (as orthophosphate), the calibration graph is linear up to 30 mg P 1-l and up to 2
