Abstract: Six inorganic anions (F-,Cl-,NO-2,PO3-4,NO-3 and SO2-4) in folia gingko were determined by ion-chromatography.An anion separation column of the model YSAB-8041A and conductivity detector were used in the determination.A mixed solution containing 5.0 mmol·L-1 Na2CO3 and 5.4 mmol·L-1 NaHCO3 solutions was used as eluant,passing through the column at a flow-rate of 1.5 mL·min-1.Linear relationships between values of peak height and concentration of the anions mentioned above were obtained with correlation coefficients ranging from 0.999 1 to 0.999 7.Detection limit (μg·L-1) were found as 2.75 (for F-),4.71 (for Cl-),9.43 (for NO-2),11.1 (for PO3-4),30.0 (for NO-3) and 22.4 (for SO2-4).Precision of the method was tested using mixed standard solution of the 6 anions with 5 successive determinations,giving values of RSD≤0.94%.Test for recovery was performed by the standard addition method,giving values of recovery in the range of 96.4%-102.3%.
