Abstract
ABSTRACTAmmonium 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.
