| Abstract: | A ion chromatography method for the determination of flue-cured tobacco leaf anions was studied. The separation of the anions was achieved in an 0.003 mol/L Na2CO3-0.006 mol/LNaHCO3 and a flow rate 1.0ml/min as gradient eluant. The method is simple and useful and has good linearity with correlation coefficients and determination 6 kinds anions at the same time. The recoveries of flue-cured tobacco leaves anions are 93%- 110%, and relative standard deviations are 0.58%-2.41%. This method was applied to determine anions in fluecured tobacco leaves during the course of developing phase with satisfactory result. |
