Microdetermination of the phosphate ion using a new reaction

Microchimica Acta Aims and scope Submit manuscript

Summary

A new method for titrimetric determination of the phosphate ion is described, based on a reaction with the sparingly soluble calcium iodate in presence of ammonia. After adding iso-propyl alcohol so that the final alcohol concentration is 65 %, and filtering, the soluble iodate in the filtrate is titrated iodometrically resulting in a 12-fold amplification of the titre in case of phosphoric acid, primary and secondary phosphates and a 18-fold amplification of the titre in case of tertiary phosphates. The results show a standard deviation of 1 %.

Zusammenfassung

Eine neue Methode zur maßanalytischen Bestimmung von Phosphationen wurde beschrieben, die auf der Umsetzung mit dem wenig löslichen Calciumjodat in Gegenwart von Ammoniak beruht. Nach Zugabe von 65% i-Propylalkohol wird filtriert und im Filtrat das Jodat titriert, wobei im Fall der Phosphorsäure, des primären und des sekundären Phosphats eine Vervielfachung auf das Zwölffache, bei tertiärem Phosphat auf das Achtzehnfache eintritt. Die Ergebnisse zeigen eine Standardabweichung von 1%.
