Actually I am done biosorption assay, heavy metals removal using silver nanoparticles.
I performed FTIR analysis of silver nanoparticles before adsorption, and FTIR analysis was also done after adsorption assay.
After adsorption I got a different FTIR spectra, some peaks shifts and peak intensity differences, these could be definitely due to metal ions.
Here I am confused how to interpret results, that what happened between nanoparticles and metal ions which caused spectral changes.
Kindly guide me on this.
Thank you.
