The way i read it, Sanctified Spells are "simply" of a different kind, neither arcane or divine, and have to be prepared to be used.
I'm inclined to say "no", for 2 reasons:
1- Although a wizard can prepare spells, in usual circumstances, he has no way of preparing a spell, if it isn't scribed in his spellbook. The basic divine classes pray for spells, so they have it easy, in this case...
2- "Arcane Preparation" allows you to prepare a spell you
know, not a random spell. If you find a way to include one of these in your spells known list, then i see no problems.
EDIT: Use a Ring of Theurgy (Complete Arcane, p. 145) permanently loaded with a sanctified spell and you're golden!
Although it would be a waste, if you ask me...
