| Abstract: | A method of determining total sulfur mass fraction in biuranate by high temperature furnace combustion infrared carbon-sulfur analyzer was established.Vanadium pentoxide in powder was used for flux,after biuranate sample was heated and burned in high temperature furnace,sulfur mass fraction in the sample was determined by infrared absorption method.The results of sample analysis have a good reproducibility.Relative standard deviation is 0.26％.The recovery of the method was in the ranges of 97.1％-103％. |
