摘要
分别采用NJ-SA-4A324型阴离子色谱柱和US 9633型阳离子色谱柱，用离子色谱法分别同时测定了烟草中的F^-、Cl^-、NO2^-、NO3^-、PO4^3-、SO4^2- 6种阴离子和Na^＋、K^＋、Mg^2＋、Ca^2＋ 4种阳离子，各离子分离良好，测定结果的相对标准偏差为0．14％～1．24％，其中Cl^-的测定结果与行业标准方法测定结果基本一致。
F^-、Cl^-、NO2^-、NO3^-、PO4^3-、SO4^2- and Na^＋、K^＋、Mg^2＋、Ca^2＋ in the tobacco were determined by ion chromatography with NJ -SA -4A324 anion elumn and US 9633 cation clumn. Both the anions and cations had good seperation and the RSD of the results were 0.14% - 1.24%. The result of Cl^- agreed with that from the standard method.
