Determination of Sodium in Light Metals and Their Alloys (I). Determination of Sodium in Calcium Metal

Tsunenobu Shigematsu and Hirozo Kimura


Abstract:

Gravimetric and colorimetric methods for the determination of a wide range of sodium in metallic calcium by means of uranyl-nickel-acetate reagent was studied. A gravimetric procedure was utilized for the determination of industrial crude calcium containing up to 1 or 2 percent of sodium, and a colorimetric procedure was utilized for the determination of microquantities of sodium in distilled calcium.
