I have electrolyzed some KClO3 solution using a platinized Ti anode (yes now a real one from GalliumGuy on ebay) and after running 12 hours at 5 Amps
I boiled off much of the water, cooled it in the fridge and then cleared it with ice-cold water sucked into a Büchner funnel repeatedly. The leftover
in the funnel appears to be sodium free. I did a flame test and saw purple flames. I see a little difference: the crystals appear to be larger.
I don't have methylene blue (with which one can test the precence of ClO4-), so is there another way to separate it ?

Decompose in boiling HCL, then recrystallize perchlorate.

You'll find more expertise on this in the energetics part of the forum. They do this stuff a lot.

dilute HCl may work, ive heard that HClO3 is unstable and breaks down practically right away in temperatures above 0*C but chlorine oxides may be a
new hazard
honestly, just go bulk and douse it with icecold water
