Research Abstract |
We developed a novel ion chromatographic system with ion-extraction device (IED), which consists of 1) extraction of ions from a sample by IED, 2) separation of ionic spices by a zwitterionic compound modified silica gel column, and 3) detection of conductivity detector. The analyte ions during the procedures are moved by water only. The conductimetric response was sensitive because the background level was almost 0. Accordingly, the IC system is suggested to be an environmental friendly method owing to low environmental impact. By using the method, we could extract and separate ions in several real water samples. Interestingly, very weak acidic anions such silicate and borate ions were not extracted by IED, while strong inorganic ions were completely extracted. The result can conduct to the online analysis for silica and borate ions in tap water and river water samples.
