Zusammenfassung
Die vorgeschlagene Kontrolle der Uranbelastung beruht auf der Durchflußanalyse mit kontinuierlicher Segmentierung. Der Aufwand ist relativ gering und auch die Betriebskosten sind niedrig. Uran(VI) kann in bis zu 60 Proben je Stunde (0,1–5 g/l U) bestimmt werden. Die Anwendung der Spektralphotometrie für die Analyse verschiedener Prozeßströme wird diskutiert. In mehrfacher Hinsicht ist das Verfahren mit anderen Methoden gut vergleichbar.
Summary
Instrumentation based on continuous segmented flow analysis is suggested for the control of uranium loading in the amine phase of solvent extraction plants processing sulfate leach liquors. It can be installed with relatively little capital outlay and operational costs are expected to be low. The uranium(VI) in up to 60 samples of extract (∼0.1 to 5 g l−1 U) per hour can be determined. Application of spectrophotometry to the analysis of various process streams is discussed and it is concluded that it compares favourably in several important respects with the use of alternative techniques.
