摘要
研究了用带电导检测器的离子色谱对米酒中阴离子 NO-3 、NO-2 进行分离测定的方法。 NO-3 、NO-2 的线性范围分别为 0 .5~ 80 mg/L 和 0 .1~ 2 0mg/L,检出限分别为 0 .5mg/L和 0 .1 mg/L。该法也适用于 SO2 -4 、Cl-的测定。
A rapid and simple metod for determination of nitrate and nitrite in arack by ion chromatography with conductivity detector was studied. A solution containing 2.8 mmol/L NaHCO 3 2.2 mmol/L Na 2CO 3 was used as eluate on a Dionex HPIC AS 3 column. The linear range for the determination of nitrate and nitrite are 0 5~80 and 0 1~20 mg/L with detection limits of 0 5 and 0 1 mg/L, respectively. This method could also be used for determination of sulfate and chloride in arack.
