My2Cents,

strange features in spectra can be also induced by mixtures of different species (especially from different oxidation states, especially at low energies)

All,
Can anyone provide some insight into the pre-edge “features” in this P XANES spectrum?
This is the P XANES spectrum we got for a recovered P-product (rich in Fe and Al) from wastewater using the AnMBR technology. During the coagulation process, our collaborators (environmental engineers) used stock solutions of aluminum chlorohydrate (ACH) and FeCl3.
 
Thanks very much.
 
Best regards, 
 
Ganga
