Determination of Four Inorganic Anions in Carbonates and Phosphates by Ion Chromatography

doi:10.7506/spkx1002-6630-201614030

Abstract

Abstract:

An analytical method using ion chromatography with isocratic elution was developed for the determination of four
inorganic anions (F-, Cl-, SO₄^2- and NO₃^-) in carbonates and phosphates. Carbonate samples were dissolved in 20 mmol/L
sodium hydroxide solution and then neutralized to pH between 4.5 and 5.5 with phosphoric acid. Phosphate samples were
dissolved with 20 mmol/L sodium hydroxide solution directly and then separated on an AS11-HC column with 20 mmol/L
sodium hydroxide solution as the mobile phase at 1.0 mL/min flow rate. The results indicated that the calibration curves
showed good linear relationship for 4 inorganic anions (r = 0.999 2–0.999 9). The limits of detection (LODs) for F-, Cl-,
SO₄^2- and NO₃^- were 2.0, 2.0, 2.5 and 2.5 mg/kg respectively. The mean recoveries at three spiked concentration levels
(low, middle, and high) were 80%–109.88%, and the relative standard derivations (RSDs) were 0.85%–4.67% (n = 6).
The proposed method is reliable, simple, convenient, sensitive, universal and reproducible, and can be applied in the rapid
determination of 4 anions in carbonates and phosphates.

Key words: ion chromatography, carbonate, phosphate, inorganic anion
