Summary

A new color reaction for the determination of gold(III) has been developed. Gold reacts with 3-methyl-4-vanillidine isoxazolone-5 in basic media at 90° to produce a pink color which is specific. Cobalt and nickel do not interfere when present upto 4 folds. Maximum tolerable amounts of other metal ions have also been studied.

Zusammenfassung

Eine neue Farbreaktion zur Goldbestimmung mit 3-Methyl-4-vanillidinisoxazolon-5 in basischem Milieu bei 90° führt zu einer spezifischen Rosafärbung. Kobalt und Nickel stören bis zur vierfachen Menge nicht. Außerdem wurden auch die tolerierbaren Mengen anderer Fremdionen bestimmt.
