离子色谱法同时测定烟草中的硝酸盐与亚硝酸盐
Simultaneous determination of nitrate and nitrite in tobacco by ion exchange chromatography
摘要
Abstract
A sensitive ion exchange chromatography method was developed for simultaneous determination of nitrate and nitrite in tobacco. Ultrapure water was used for ultrasound-assisted solvent condition. Extract liquor were separated using anion exchange column. Nitrate and nitrite ion were then detected by conductance detector. Results showed that linear relations were observed in the range of 0.032~1.600 mg/L for nitrite,and 0.800~40.000 mg/L for nitrate. Detection limits were 1.06 mg/kg for nitrate and 1.23 mg/kg for nitrite. Recoveries were 96.3%~99.0% for nitrate and 96.1%~101.6% for nitrite. Both RSDs were below 5%.关键词
