removing tartaric acidand aluminium sulphate from baking powder

friend recently i buyed some baking powder.for some experiment. i was unable to find baking soda so i buyed baking powder but baking powder contains tartaric acid.and of some other brand it contains aluminium sulfate. so friends is there any way to remove them from sodium hydrogen carbonate.

React with K2CO3, filter, then recrystalize at low temperatures.

As soon as i add water to sodium hydrogen carbonate mixed with tartaric acid or aluminium sulphate. Reaction takes place and it forms sodium tartarate. I want to extract NaHCO3 not Na2CO3 . Which will be extracted after adding K2CO3. Also i dont have K2CO3 currently so tell any other way

Aluminium sulfate, you got to be kidding me!!

Sure you aren't refering to ammonium sulfate/carbonate..?

Wouldn't eat anything with Al compounds in it unless trace amounts.

I believe you.

But it is kinda moronic to eat something that toxic which also is linked to Alzheimer even though the end products may be "insoluble" in water.

If that was my only choice of leavening agent I would rather build an airtight oven and apply some vacuum......

As far as I know baking powder in scandinavia is tartaric acid and sodium bicarbonate, and perhaps some fillers like starch and the like.

Back to the topic at hand, give up.... It would take you lots of effort to separate those substances plus the additives.

So there is no way to separate them
