Abstract

Abstract

In order to accurately measure the content of cadmium in uranium silicon compounds and provide reliable data for quality control and evaluation of nuclear fuel materials, graphite furnace-atomic absorption spectroscopy is used to study the determination of cadmium in uranium silicon compounds. By exploring the dissolution condition, the best parameter conditions of the instrument and the matrix influence behavior, the best experimental parameters were obtained, and the precision and addition recovery experiments were carried out. The experimental results show that when the detection range of the mass fraction of cadmium is 0.1-1.0 µg/g, the recovery rate of the method is 87%-110 %, and the relative standard deviation is better than 15%. This method is accurate and convenient, meeting the determination of trace cadmium in uranium and silicon compounds, and can be used in scientific research or production.
