| 英文摘要 | Coal fly ash (CFA) and coal ash (CA) as a result of coal firing from power generation plants caused global environment contamination. It is important for environment science to monitor the migration and emission path of CFA and CA. Both radiogenic Sr and Nd isotope have proved to be powerful and sensitive tracers to address this issue. Unfortunately, up to now, high precision data of Sr-87/Sr-86 and Nd-143/Nd-144 isotope ratio for CFA and CA are rare to be reported. Hence, to boost up Sr-Nd isotope application in environmental science, it is indispensible and urgent to report a suit of high precision data for Sr-Nd isotope ratio and relative Rb, Sr, Sin and Nd element content for CFA and CA reference materials. In this work, we determined Sr-Nd isotope ratios for four CFA and CF reference materials using thermal ionization mass spectrometry (TIMS). Reference values for these four CRMs (GBW08401, GBW11124, GBW11125d and JCFA-1) span a wide range in Sr-87/Sr-86 ratios from 0.705700 to 0.723650 and from 0.511950 to 0.512680 for Nd-143/Nd-144. The external reproducibility (2 SD, n = 8) of four CRMs vary from 0.000014 to 0.000028 for Sr-87/Sr-86 and from 0.000008 to 0.000010 for Nd-143/Nd-144. The concentrations of Rb, Sr, Sm and Nd elements of four CRMs were determined using ID-TIMS method. Considering all results, the reproducibility (1 RSD, n = 4) of elemental content was < 0.6% for Rb and Sr, 0.4% similar to 1% for Sm and Nd. This indicates homogeneous distribution of Rb, Sr, Sm and Nd elements in these four CRMs. Hence, this suit of reference materials can be used for materials with different CFA and CA matrix composition for justification and quality control measures of radiogenic Sr and Nd isotope analyses. This study is the first to report the Sr Nd isotopic compositions of these CFA and CA reference materials. |
