A simple quantitative method is developed for the determination of trace amount of chloride in uranium without preliminary separation. The reactions are realized by mixing the sample with saturated mercury thiocyanate alcohol solution and 0.325 M ferric ion in 5.52 M perchloric acid solution. The wavelength 465 m μ is used for the determination of chloride. The interference of uranium is negligible for uranium concentration less than 400 ppm . When uranium concentration ranges from 400 to 1.2×10 4 ppm , the interference can be calculated based on the constancy of molar absorptivity of uranium solution at wavelengthes 465 m μ and 415 m μ, therefore, a correction can be made for the determination of chloride. Interference of other factors were also investigated.
