Rted by [115]. Similarly, the usage of PANI py copolymer nanofibers for the removal of cobalt ions Co (II) from aqueous solutions was reported by [144]. They emphasized the optimistic part of temperature around the adsorption procedure and reported 99.68 removal efficiency to get a 100 mg/L Co (II) concentration at the optimum operating circumstances. Similarly, the removal of Congo red (CR) from aqueous solutions using PANI py nanofibers was reported by [131] inside a batch adsorption model, indicating higher removal efficiencies for CR at low remedy pH. They also reported excellent fitting of your Langmuir isotherm equilibrium model and pseudo-second-order kinetic model to their experimental data. A greater adsorption capacity was observed for PANI nanofibers (270.27 mg/g), compared with Ppy nanofibers (222.22 mg/g). Further utilization of conductive polymers as MCP-1/CCL2 Proteins Recombinant Proteins adsorbents for nitrates from wastewater was reported by [145], applying polyaniline and polypyrrole as adsorbents. They reported that the Langmuir isotherm model fitted properly the experimental data and that the adsorption approach followed the pseudo-second-order kinetic model. The nature of the adsorption of nitrates on PANI and Ppy was spontaneous. Having said that, larger adsorption capacities for nitrates were observed by PANI, compared with Ppy. The removal of Congo red was reported for PANI and Ppy adsorbents in yet another paper by [146], who observed that removal efficiencies improved with increasing speak to time and adsorbent dosage. They reported good fitting on the Langmuir equilibrium isotherm and pseudosecond-order kinetic models with their experimental data. In another research report, methylene blue (MB) removal using polyaniline and polypyrrole macro-nanoparticles was reported [147]. The reported maximum adsorption capacity for the synthesized nanoparticles was 19.2 mg/g of MB/g of polymer. In addition, a detailed review around the utilization of conducting polymers as adsorbents for the removal of textile dyes was reported by [57]. Many surface morphologies possessed by polypyrrole-modified adsorbents are presented in Figure eight under.Polymers 2021, 13, x FOR PEER REVIEWPolymers 2021, 13,16 of(a)(b)(c)(d)(e)(f)(g)(h)Figure eight.
