説明
A study to find a better mobile phase for use in the rapid determination of inorganic anions such as fluoride, chloride, nitrite, phosphate, nitrate and sulfate ions by indirect photometric ion chromatography is presented. The eluent optimized was a weak-alkaline (pH 7.3) buffer solution containing 0.7 mM potassium hydrogenphthalate-0.1 mM sodium tetraborate-0.5 mM boric acid-0.1 mM HEPPS-0.05 mM sodium hydrogencarbonate-5 % butanol. The problem of the system peak otherwise encountered was eliminated by judicious choice of the alkalinity of the buffer solution. The eluent did not show any pH drift typically caused by dissolution of carbon dioxide, and was able to separate the phosphate ion completely from the chloride. Whole anions above described were determined within 15 min.
