| Abstract: | An ion chromatography (IC) was established for the separation and determination of Sodium cyclamate and Potassi-um sorbate in drinks. A Dionex IonPac AS19 (4 mm ×250 mm,5μm) was used as chromatographic column,with 20 mmol/L KOH as mobile phase at flow rate of 1.0 mL/min,and the suppressor electric current was 50 mA,the column temperature was 30℃,pressure was 1668 Psi. Separation of 2 additives was simultaneously achieved in 8 min. The results showed that the method was rapid, simple, sensitive, and could meet the need of practical work. |
