摘　　要：采用酸法消解样品,分析了用ICPAES法测定环境土壤和地下水中Sr、Nd、Ce的工作条件。方法对Sr、Nd、Ce的检出限分别为0.001、0.04和0.04μg/mL,相对标准偏差<5%。用国家标准物质GSS1和GSS8的测定结果表明,测定值与推荐值一致,能够满足环境土壤和水中Sr、Nd、Ce的测定要求。A nearly thorough analysis is paid to the determination of Sr,Nd and Ce in environmental soils using ICP-AES. The detecable limits are 0.001, 0.04 and 0.04 μg/mL, respectively, for Sr, Nd and Ce, with a relative standard deviation of <5%. The GSS-1 and GSS-8 based determination indicates a good agreement between measured and recommended values, meeting the needs of the determination of Sr, Nd and Ce in the envirommental media.
