Abstract A simple procedure is described for determining sodium in sodium hydroxide-treated rice straw and rye grass, lye-peeled potato wastes, and brine-frozen vegetables. Samples containing ≤4% sodium were extracted with 0.05M ammonium carbonate and the extracts were analyzed directly by using a sodium ion selective electrode over the range 10−4 to 10−2M sodium ion. Comparable analyses of the same extracts by atomic absorption spectrometry agreed to within 10%. Recovery of sodium added to control rice straw was 102%.
