本文叙述了一种自动测定铀(Ⅶ)的方法。用煤油等为稀释剂的三烷基胺作有机相从硫酸浸出液中萃取铀(Ⅶ)。此法采用连续分流技术,所用设备可用商品部件组装。由于该法不受其他离子特别是硫酸根的干扰,因而适用范围较广。测定速度为每小时60个样品时,能测定萃取后有机相中0.5—5克/升的铀。对此法稍加改进,即可用于测定浓度更低的样品。 This article describes a method for automated determination of uranium (Ⅶ). Uranium (Ⅶ) was extracted from sulfuric acid leachate by using trialkylamine as a diluent, such as kerosene. This method uses continuous shunt technology, the equipment used for the assembly of parts. As the law is not subject to other ions, especially sulfate interference, and thus a wider scope of application. When measured at 60 samples per hour, 0.5-5 g / L of uranium in the organic phase after extraction can be measured. This method a little improvement, you can use for the determination of lower concentrations of the sample.
