reactive phosphorus in water samples is described. The system includes a liquid waveguide long pathlength cell connected to a charge coupled device (CCD) spectrophotometer. Calibration was linear up to 500 µgPL−1, with a detection limit of 17 µgPL−1 and a quantification limit of 56 µgPL−1. An injection throughput of 60 determinations h−1 and repeatability (R.S.D.) of 2.2% were achieved. Potential interference f...
