Spectrophotometric microdetermination of copper in biological samples by an improved version of Matsuba and Takahashi's method

  • Published:
Microchimica Acta Aims and scope Submit manuscript

Summary

The determination of microgram amounts of copper with N,N,-N′,N′-tetraethylthiuram disulphide is described. Three different procedures allow copper determination in various biological samples and in water. The method is simple, rapid and precise, and gives a detection limit similar to that obtained by atomic-absorption spectrometry.

Zusammenfassung

Die Bestimmung von Mikrogrammengen Kupfer mitN,N,N′,N′-Tetraäthylthiuramdisulfid wurde beschrieben. Drei verschiedene Verfahren ermöglichen die Kupferbestimmung in verschiedenen biologischen Materialien und in Wasser. Die Nachweisgrenze dieser einfachen, raschen und genauen Methode entspricht der der Atomarabsorption.
