Simultaneous determination of fluoride, chloride, nitrite, bromide, nitrate, phosphate and sulfate in aqueous solutions at 10−9 to 10−8% level by ion chromatography

Abstract The method of simultaneous determination of F − , Cl − , NO 2 − , Br − , NO 3 − , HPO 4 2− , SO 4 2− ions on trace level by IC using preliminary concentration and water removal from concentrating column was proposed. Detection limits were 10 −9 to 10 −8 % for sample volume 10 ml depending on the anion.
