Zusammenfassung

Ein neues komplexbildendes Harz wurde aus Amberlyst A-26 und 8-Aminonaphthalin-2-sulfonsäure (ANS) hergestellt. Dieses mit ANS beladene Harz ist stabil und widerstandsfähig gegen Mineralsäuren. Die Anwendung zur Silberbestimmung mit AAS in Kupfererzen wird beschrieben.

Summary

A new chelate-forming resin was prepared from Amberlyst A-26 and 8-amino-naphthalene-2-sulphonic acid (ANS). ANS-loaded resin is stable and resistant to mineral acid. The application of the resin to the determination of silver in copper ore is described.
