摘要
Abstract
The method of determining water content in uranium dioxide with Karl Fisher coulometer is introduced, and the instrument conditions were optimized. Air is taken as carrier gas, carrier gas f low rate is 40-60 mL/min, the temperature of Cassette furnace is 200 ℃, stirring rate of titration cell is 300-900 r/min, the extraction time is 800 s. Under the above conditions, water content in uranium dioxide was determined. The detection limit of the method is 38 μg/g, the relative standard deviation is less than 1. 76%(n = 6), and standard addition recovery is 93. 6%-99.1%.关键词
