Major ions were analyzed in the Department ofGeology,Renlou Coal Mine.REE concentrations of groundwater were determined after pre-concentration by
liquid-liquid extraction,and analyzed by inductively coupled plasma mass spectrometry in the State Key Laboratory of Geological Processes and
Mineral Resources,China University of Geosciences(wuhan).Analytical process followed the method reported by SHABANI et al .The isobaric interference of BaO to Eu had not been well corrected,leading to the useless Eu among these REEs .The analytical precision for all REEs except for Eu was 10% or better.REEs of rocks
were analyzed with PE Elan 6000 ICP-MS at the Key Laboratory of Isotope Geochronology and Geochemistry,CAS.The relative derivations were less than 5%,and detailed analytical procedures were referred to LIU et al.
答案
分析了主要离子在地质系,任楼煤矿.
稀土元素浓度的确定地下水的各种之后
液-液萃取,并分析了电感耦合等离子体质谱法在国家重点实验室的地质过程和
矿产资源,中国地质大学(武汉).
分析过程由大家跟着方法报道et al.
保的等压的干涉欧盟没有被纠正,导致了无用的欧盟在这些稀土元素.
分析的精确度,REEs除了欧盟是10%或者更好.
里斯的岩石
进行了分析与PE Elan 6000 icp - ms在重点实验室同位素地质年代学和地球化学,CAS.
相对派生不到5%,并详细分析程序被称为刘在所有.
举一反三
已知函数f(x)=x,g(x)=alnx,a∈R.若曲线y=f(x)与曲线y=g(x)相交,且在交点处有相同的切线,求a的值和该切线方程.
