SWIM is thinking about making a fume hood with a carbon filter as a part of the exhaust. However, a proper carbon filter is too expensive and too hard to find in this area.
He is thinking to make a filter with some activated charcoal as activated carbon. I am thinking if it is possible to activate the charcoal by washing the some barbecue charcoal with some concentrated HCl. I am thinking if the following is a possibility:
1. Since CaCl2 and HCl have the negatively charged atom, Cl-. Can I concentrate 35% HCl to higher concentration by putting some/ lots of CaCl2 in the HCl.
2. Soak the barbecure with the concentrated HCl to make activated charcoal.
Do I have to use concentraed acid to make activated charcoal? Is it possible to concentrate HCl with the above method?
Thanks to the people who answer my questions.
