A potentiometric method for the determination of uranium by stannous chloride reduction
- 26 Downloads
A potentiometric method has been developed for the determination of uranium using stannous chloride as reductant. The oxidation of excess stannous chloride was accomplished with an excess of sodium nitrite, the excess of which was destroyed by sulfamic acid. The U(IV) was then determined by potentiometric titration with standard potassium dichromate. For 3–5 mg amounts of uranium the precision obtained was better than 0.3%.
