Separation of magnesium from manganese and zinc

Abstract EN

Magnesium ions, with concentration as low as 10-4 M have been quantitatively separated from Mn (II) an Zn (II) ions by precipitations with some halogen substituted of Diphenylthiocarbazon in a buffered solution of about 50 % V / V aqueous – dioxin .

As a precipitant the di-p-iodophenylthiocarbazone in dioxin solution was employed .

The use of this legends is promising for both qualitative test and quantitative determination of traced of magnesium.

Preliminary work with the di-p- fluoric, di-p- calico, di-p-brome, and di-m-trifluoromethyl phenyl thiocar bazone indicated the formation precipitates analogous to the magnesium di-p-iodo- compound.
