摘　　要：锶是石膏及石膏制品中常见的杂质元素,锶的同位素中锶85、锶89和锶90等都具有放射性且半衰期较长,对人体有较大危害。传统的测定锶含量方法不适宜石膏及石膏制品中锶含量的测定;采用电感耦合等离子原子发射光谱(ICP-AES)法来测定石膏及制品中锶含量,具有快速、准确、重现性好的特点,符合检验检疫行业要求。Strontium is a comman impurity element in gypsum and gypsum products.It does great harm on human body because its isotopes,such as Sr 85,Sr 89,and Sr 90,have a longer radioactive half-life.Traditional method of determination of strontium content is not suitable for gypsum and gypsum products.Inductively coupled plasma atomic emission spectrometry（ICP-AES） was used to determine strontium content in gypsum and gypsum products.This method is fast,accurate,and reproducible,which can meet the requriements of inspection and quarantine.
