Yes, but it would be more practical to first distill it by itself to reach the azeotrope, then use sulfuric acid to reach near anhydrous.

I found in the literature table of dryers activity for nitric acid:
Al(NO3)2>Fe(NO3)3>Mg(NO3)2>Ni(NO3)2>H2SO4>LiNO3>Al2(SO4)3>Zn(NO3)2>Ca(NO3)2>H3PO4>Cd(NO3)2>NaNO3>KNO3.
Has anyone tried to distill nitric acid with LiNO3? LiNO3 is inferior to Mg(NO3)2, but it does not decompose when dehydrated. I could not dehydrate
Mg(NO3)2 2H2O to anhydrous salt without obtaining NOx. The distillation with Ca(NO3)2 gives only 90% nitric acid.
