The experiment aims to teach undergraduate chemistry students about various FTIR sampling techniques used in industry and research.
Used modern infrared sampling techniques including DRIFTS and ATR-FTIR.
Analyzed powder and aqueous-phase samples for structural characteristics.
Studied ethylenediaminetetraacetic acid (EDTA) sodium salts and its complexation with lead ions.
Students assigned vibrational bands in spectra and analyzed band shifts.
Students successfully identified vibrational bands in FTIR spectra.
Evidence of complexation between EDTA and lead ions was observed through band shifts.
Comparative analysis between transmission and reflectance sampling techniques showed notable differences.
