Conclusions Conductive polymers and their composites are identified to be effective adsorbents for numerous forms of pollutants and contaminants. This is largely resulting from their interesting redox characteristics and the presence of N, S, P, and O components in their chemical structure. One of the most predominant reported mechanisms for organic dyes removal are interactions, hydrogen bonding, hydrophobic interactions, acid ase interactions, and electrostatic interactions. As for the heavy metal ions removal, one of the most widespread mechanisms are electrostatic attraction, ion exchange, chelation, and reduction. Among the heavy metals, removal of Cr (VI) is the most broadly studied contaminant, while amongst the organic dyes, methylene blue is reportedly the most broadly studied pollutant. Overall, it may be concluded that modification by conductive polymers of numerous types of possible adsorbent materials results in substantial improvements within the adsorption rates and maximum adsorption capacities on the unmodified adsorbents. Among the conductive polymers, polyaniline and polypyrrole have been extensively studied as possible adsorption enhancers (major to considerably high maximum adsorption capacities), compared with polythiophenes. Hence, polythiophenes and their derivates may perhaps present opportunities for additional exploration and research.Funding: This study was funded by the Deanship of Scientific Investigation at King Khalid University, Saudi Arabia, via research groups program below grant number R.G.P 1/196/41.
