摘要
采用离子交换树脂处理以除去干扰样品的氢氧根离子，很好地消除了基线效应。以Dionex AS9-HC作为分离柱，9mmol／L碳酸钠溶液作为淋洗液，抑制电导检测。该方法的结果令人满意，基线平直，检出限低，回收率在96％-104％之间，对于测定浓碱中的阴离子是一种很有效的方法。
Anion exchange resin was used to remove hydroxyl ions, which effectively eliminate the domino effect of baseline. Dionex IonPac AS9-HC column was used for separation and 9 mmol/L sodium carbonate solution was used as the eluent to suppress conductivity detection. The results were satisfactory and the detection limits of these anions were low. Recoveries from spiked samples were between 96% and 104% . Compared with other methods, it is an efficient and simple method for the determination of anions in sodium hydroxide. This method can be used for determination of anions in high alkali solution and solid alkalis.
