EFFECT OF PLUTONIUM ON COLORIMETRIC IRON ANALYSIS

摘要

The interference of plutonium in the colorimetric analysis of iron with o-phenanthroline has been quantitatively determined. Using iron-free Plutonium, the extinction coefficient varies between 0.078 and 0.038 ml./nig. when the plutonium concentration in a 10 ml. sample is changed from 0.1 to 0.8 Eg/ml. The ex¬tinction coefficient for iron is 2-4000 times greater than that for plutonium.
