| Abstract: |
| This paper using the HF-HCl-HNO3 system with high-pressure closed digestion for samples pre-treatment, and utilizing Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-AES) for determination the 18 multielements in the Shale reference material. Optimal conditions were determinated and the best spectral lines were selected. The experimental results show that, good linear relationship with linear correlation coefficient r>0.999 8. The detection limits of these ten elements are low, the precision of RSD less than 2%(n=6), The quantitation values matched the certified value of manganese nodule GBW07296 and Co-rich crust GSMC-1. This method has the advantage of providing a simple,simultaneous determination of multiple elements,along with having a wide linearity range and low detection limit,which can be widely used in geological shale samples. |
