| Abstract: |
| An automatic solid phase extraction system was developed to separate iron from geological samples. The system has four parallel channels and can process four samples at a time. One extraction procedure will take 24 minutes for 4 samples. The iron was separated from granite (GBW07103)with AG1-X8 anion resin. Iron can be converted into anionicScomplex in 6 mol L-1 hydrochloric acid and adsorbed on AG1-X8 anion resin. While iron can be eluted with 8 mol L-1 Nitric acid and H2O. The recovery of iron was 96%-107%. It eliminates the influence of matrix, improves sample processing efficiency, reduces the risk of human contamination, and is a diversified sample processing tool. |
