Abstract

A procedure for the automatic photometric determination of phosphate ions in natural waters was developed, based on the formation of a colored ion associate of the reduced form of phosphomolybdic heteropoly anion with a polymethine dye, Astra Phloxine. The detection limit was 5 μg P/L at the sample volume of 0.3 mL.
