【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-、C l-、NO2-、NO3-、PO43-、SO42-6种阴离子和Na+、K+、Mg2+、Ca2+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C l-的测定结果与行业标准方法测定结果基本一致。更多还原

【Abstract】 F^-,Cl^-,NO₂^-,NO₃^-,PO₄^3-,SO₄^2- and Na⁺,K⁺,Mg²⁺,Ca²⁺ in the tobacco were determined by ion chromatography with NJ-SA-4A324 anion clumn 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.更多还原
