Summary

Polarography is attempted in the study, at trace level, of zinc phosphate precipitate which is not sparingly soluble. The choice of the supporting electrolyte is very important as it functions also as a coagulating agent. In contrast to conventional polarography, the supporting electrolyte concentration was found to be critical. The effect of pH, temperature, volume, time, stirring, etc. was studied. Complete precipitation was obtained under proper conditions for 40μg/ml of zinc solution.

Zusammenfassung

Das deutlich lösliche, in Spuren gefällte Zinkphosphat wurde polarographisch untersucht. Die Wahl des Trägerelektrolyten ist hierbei sehr ausschlaggebend, da er auch koagulationsfördernd wirkt. Im Gegensatz zur konventionellen Polarographie erwies sich die Konzentration des Trägerelektrolyten als kritisch. Der Einfluß des pH, der Temperatur, des Volumens, der Zeit, des Rührens der Lösung usw. wurde untersucht. Unter geeigneten Bedingungen wurde die vollständige Fällung einer Lösung von 40μg Zn/ml erreicht.
