Characterization of the PPy/o-MWCNT nanocomposite was carried out using attenuated total reflectance infrared spectroscopy, Raman analysis, diffuse reflective ultraviolet–visible spectroscopy, powder X-ray diffraction, thermogravimetric analysis, scanning electron microscopy (SEM), energy dispersive analysis of X-rays (EDAX), transmission electron microscope (TEM) and selective area electron diffraction pattern (SAED). The obtained results confirmed successful synthesis of PPy/o-MWCNT nanocomposite. TEM provided the information about the wrapped tubular carbon nanotubes present in the polymer matrix and SAED pattern additionally confirms the crystalline pattern of the metal-loaded adsorbent. SEM images showed the o-MWCNT even dispersion of polymer matrix beyond the magnification of 200–500. EDAX data revealed the loading of metal ions onto polymer surface which was confirmed due to the presence of corresponding. The PPy/o-MWCNT nanocomposite was used as an efficient adsorbent for the removal of Pb\u003csup\u003e2+\u003c/sup\u003e, Ni\u003csup\u003e2+\u003c/sup\u003eand Cd\u003csup\u003e2+\u003c/sup\u003eions in aqueous media. Batch experiments show maximum adsorption capacity of PPy/o-MWCNT nanocomposite on Pb\u003csup\u003e2+\u003c/sup\u003e(408 mg/g), Ni\u003csup\u003e2+\u003c/sup\u003e(409 mg/g) and Cd\u003csup\u003e2+\u003c/sup\u003e(392 mg/g). The heavy metal ions adsorption on PPy/o-MWCNT nanocomposite shows fast process and the kinetics followed a pseudo-second-order rate equation (\u003ci\u003eR\u003c/i\u003e\u003csup\u003e2\u003c/sup\u003e ≈
