- 中文摘要: 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 0.325M ferric ion in 5.52M perchloric acid solution. The wavelength 465mμ is used for the deterimination 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.. ppm, the interference can be calculated based on the constancy of molar absorptivity of uranium solution at wavelengths 465mμ and 415mμ, therefore, a correction can be made for the determination of chloride. Interference of other factors were also investigated.
