Good day, I am obviously a "noob" but have been studying the chemistry and procedures involved in AR digestion of gold, and nitric acid digestion/ recovery of silver.
Could anyone kindly recommend to me advice on face masks/respirators to use when working with AR or Nitric acid fumes? I eventually planning on rigging up a fume hood, but in the meantime is a good respirator a good substitute?
Thanks !
