| Abstract: |
| A rapid method was developed for determination of xylitol in the treating burley tobacco by ion chromatography.No complicated sample pretreatment was required.The quantitative results were obtained by the external standard method.The method has good linearity with correlation coefficient of 0.9995 in the concentration range from 1.025×10-6 to 1.025×10-7.The recovery was 94.3% to 102.5%,and the RSD was 0.08%.The method was shown to be rapid,accurate,robust,and convenient,and it could be applied to the measurement of xylitol in the treating burley tobacco with satisfactory results. |
