| 摘 要： | 用发射光谱法测定结晶硫酸镍中Ｃａ，Ｍｇ，Ｃｕ，Ｆｅ，Ｐｂ，Ｚｎ等杂质元素，加入ＮａＣｌ为缓冲剂改善杂质元素的激发行为，以提高分析的灵敏度。用交流电弧激发，以镍为内标，一次摄谱，可同时测定上述六种元素。此法快速、准确，满足实际需要。

| Abstract: | The impurities of Ca,Mg,Cu,Fe,Pb and Zn in Nickel sulfate are determined by using emission spectrum under 5.5-6 A of current and 5 s of exposure time.Nickel is used as internal standard element and NaCl serves as spectral buffer.This method is proved as accurate,easy and quick. |

| Keywords: | emission spectrum nickel sulfate buffer alternating current arc |
