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。
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.
