| titleOfInvention | Method and apparatus for highly sensitive separation and measurement of silicate ions |
| abstract | PROBLEM TO BE SOLVED: To provide a silicate ion separation measuring method and apparatus capable of measuring silicate ions with high sensitivity without being disturbed by coexisting anions. SOLUTION: An ion exclusion ion chromatography that selectively and highly sensitively measures silicate ions in test sample water such as drinking water and environmental water, using water as an eluent and weakly basic. By removing ions of anion exchange resin column and weak acid cation exchange resin column, strong acid ions and weak acid ions (hydrogen carbonate ion, aliphatic carboxylate ion, etc.) are removed, and only silicate ions are separated. Thereafter, a method and an apparatus for separating and measuring silicate ions, which are measured by conductivity or UV absorbance. [Effect] 0.01-2.0 mM silicate ions contained in seawater, river water, etc. can be accurately quantified with no (low) pollution. [Selection] Figure 3 |
