摘要 氯化铵是一种广泛使用的无腐蚀性、无毒化学品。当与蛋白质接触时，NH4Cl 是非破坏性的，并且允许更柔和的条件来标记有机物质。这些特性使 NH4Cl 适用于多个领域，例如药品生产、低本底研究等。为此，可以应用多种纯元素。为了获得纯元素，必须将其分离（纯化）。元素分离最成功的方法之一是离子交换。在这项工作中，我们通过 ICP-MS 研究了 60 种元素在不同浓度 NH4Cl 溶液的阴离子交换 (Dowex 1-x8) 和阳离子交换 (Dowex 50w-x8) 树脂上的分配系数。
ABSTRACT Ammonium chloride is a widely available non-corrosive and non-toxic chemical. When in contact with protein NH4Cl is non-destructive and allows softer conditions for labeling of organic substances. These properties make NH4Cl appropriate for use in multiple areas such as pharmaceutical production, low-background research, etc. For such purposes, a multitude of pure elements could be applied. In order to obtain pure elements their separation (purification) is necessary. One of the most successful methods of elements separation is ion exchange. In this work, we study the distribution coefficient of 60 elements on anion exchange (Dowex 1-x8) and cation exchange (Dowex 50w-x8) resins with NH4Cl solutions with varying concentrations via ICP-MS.
