摘要
目的:分析不同产地石膏中无机元素的含量差异。方法:湿法盐酸-硝酸对石膏样品进行消解,利用电感耦合等离子发射光谱法(ICP-AES)测定其无机元素的含量。结果:检测到了铜、钾、镁、锰、钠、钙、硫、锌、铁、铝和铬等15种无机元素,其中铁、镁两种元素的含量差异最大。结论:不同产地石膏中无机元素的含量差异较大,可能与其产地有关。
Objective：To analyze the inorganic elements in Gypsum Fibrosum from different area.Method：ICP-AES was used to analyze the inorganic elements in Gypsum Fibrosum together with HCl-HNO3 digestion.Results：15 kinds of inorganic elements（Cu,K,Mg,Mn,Na,Ca,S,Zn,Fe,Al,Cr et al）were detected and the content difference of Fe and Mg in Gypsum Fibrosum was more great.Conclusion：The content difference of inorganic elements in Gypsum Fibrosum may be correlate to its area.
