PURPOSE:To considerably efficiently adsorb, recover and condense a stock solution of low concentration of ion in water and to measure the concentration of the stock solution. CONSTITUTION:A dilute ion solution is filtered by one or a plurality of cations, anions and a porous film of chelate exchange function. The ions adsorbed by the porous film are detached and condensed by a regeneration solution and the concentration of the ions is detected. Accordingly, the concentration of ions in the original dilute ion solution is measured. In this manner, it is possible to condense a dilute solution 1000 times or more and to specify the concentration of a stock solution with 1% or lower errors. |
