Determination of bivalent cationic impurities in sodium chloride by atomic absorption, and their distribution in the recrystallized salt.
Bivalent cationic impurities present in NaCl crystals were determined quantitatively by atomic absorption, 1.71M NaCl solutions (10% w v ) being used without pretreatment. The sensitivity for several cations was 50-60% of that in pure water solutions. The analyses revealed a non-homogeneous distribution of the impurities, due to differences in their activity during the process of crystallization.
