excuse me

can somebody help me with this

Al + KOH + H₂O = K[Al(OH)₄] + H₂

i want to regeneration the K[Al(OH)₄] back to KOH, so i don't have to buy KOH every single time.

thanks before

I think this will be more expensive, as to buy new KOH.

Probably you can add K₃PO₄ and get precipitation of AlPO₄ and KOH will be formed back.

K[Al(OH)₄] + K₃PO₄ => AlPO₄ + 4 KOH

After filtering the AlPO₄ you have new KOH.
