| Abstract |
| A simple flame photometric method for the determination of calcium
in bauxite samples has been developed. Aluminium and titanium
which interfere by reducing the Harne intensity of calcium due to the
formation of aluminium or titanium spinel with calcium have been
sequestered by the addition of magnesium which releases the calcium
from the spinel. The method does not involve prior separation of
aluminium or titanium and thus is advantageous over the lengthy and
time-consuming conventional classical methods. The results of analysis
of a number of bauxite samples agree favourably with the
certified values. The method employs only a simple filter type flame
photometer which most of the laboratories of our country can
provide. |
