Method of pre-treating a sample for metal analysis, the sample including a volatile alkali, by permeating the volatile alkali through a gas permeable membrane, dissolving the volatile alkali in an absorbent, passing ions through a first cation exchange membrane in electrical contact with an anode, reacting the volatile alkali with the ions, and passing the reacted volatile alkali through a second cation exchange membrane in electrical contact with a cathode, whereby the volatile alkali is removed from the sample. |
