Thermometric Titration of Sodium, Aluminum and Fluorine
Jul 11 2008
A typical example of a thermometric titration is the less well-known
exothermic reaction in which the mineral elpasolite (NaK2AlF6) is formed
from sodium, potassium, aluminum and fluoride ions. The industrial
determinations of sodium, aluminumand fluoride are based on this reaction; these are all known as versions of the «elpasolite method».
With the aid of thermometric titration, the elpasolite method offers a quick, reliable and extremely accurate method for determining sodium, aluminum and fluoride ions in numerous different sample matrices.
The 859 Titrotherm from Metrohm is the suitable favourably-priced instrument for these determinations.
