| Abstract: | The difluorourea content in aqueous solution was determined by using iodometry. The influence of acids, reaction temperature and time on the test results was studied. The determination method of difluorourea content was established. The optimum test conditions are mass fraction of 50% of sulfuric acid, reaction temperature of （35± 2）℃and reaction time of 20-25 min. |
