Determination of Sodium in Light Metals and Their Alloys (II). Determination of Sodium in Aluminium, Magnesium and Their Alloy

Tsunenobu Shigematsu and Hirozo Kimura


Abstract:

A sensitive colorimetric method for sodium by means of uranyl-nickel-acetate reagent have been applied to the analysis of sodium in aluminium, magnesium and their alloys.
Aluminium and its alloy were dissolved, and after aluminium was removed as AlCl3·6H2O by saturating with hydrochloric acid gas or adding concentrated hydrochloric acid, sodium in the solution was determined colorimetrically. Under suitable condtions, less than 200 milligrams of magnesium did not interfer with the determination of microgram quantities of sodium; thus sodium in magnesium was directly found.
