摘　　要：本文通过研究ICP-AES法测定工业盐中钾含量时,不同雾化器的选择、洗涤时间长短对检测结果的影响,通过测定样品标准回收率来验证不同雾化器和不同洗涤时间对检测结果的影响,从而得出塑料雾化器(四氟乙烯材质)比玻璃雾化器更适合用于钾的测定,洗涤时间短测定的钾含量偏高。This paper studies the influence of different atomizers and washing time on the detection results when the ICP-AES method is used to determine potassium in industrial salt.According to the recovery rate,the plastic(tetrafluoroethylene)atomizer is more suitable for the determination of potassium than the glass atomizer,and the potassium content measured in the short washing time is higher.
