Abstract A virgin sample of pure polyvinyl alcohol (PVA) in combination with other polymeric samples containing pre-calculated amounts of lepidium sativum natural plant seed extract was successfully prepared. Structural modification was investigated through a combination of both Fourier transformation infrared (FT-IR) combined with X-ray diffraction (XRD). Both techniques indicate interaction and complexation of the polymeric matrix through changes in vibrational bands at 1331 and 849 cm−1 owing to the CH2 wagging vibration and carbon stretching vibrations respectively. EDAX analysis supported with atomic absorption experimental data were used to investigate the structure and type of elements present in the natural seeds. Obtained data explain the complexation process between the polymeric material and plant extract attributed to the presence of Fe+2 ions even in ppm level.
