Dear members of the mailing list:
This year we have applied the synchrotron radiation and get the chance to Beijing Synchrotron Radiation Facility at beamline 1W1B-XAFS. It is the first time to use this equipment to measure our samples. We communicate with the beamline staff for some guideline and help, but they also do not have much experience on soil samples. Would you like give us some suggestions? If you could, can you supply me some resources like sample preparation or others?
Now I try to use synchrotron radiation to elucidate some phenomenons of heavy metals in mining area soil. In my soil sample, the Zn is about 498ppm and the Cu is about 562ppm, the first step I focus on Zn but the copper concentration is higher than Cu. Will copper interfere zinc If I use XAFS to measure the Zn?
I plan to use fluorescence detection. The Fe in the sample is at high concentrations (85g/kg), from some literature that might be an issue. Would you like to give me some suggestions in the sample preparation and measurement?
