“…In addition, the modification of phosphorylated cotton fabric with polyaniline displayed greater improvement in Pb 2+ ions adsorption capacity, where it recorded 363% (250 mg g −1 ) compared to UC. Also this recorded adsorption capacity (250 mg g −1 ) for C‐Ph‐PANI is very high in comparison with previous studies where the maximum adsorption capacity was 63.60 mg g −1 for Pb 2+ ions by using used polyaniline synthesized on hallow kapok fiber [ 32 ] and 14.33 mg g −1 for Pb 2+ by using polyaniline graft modified chitosan. [ 33 ] The higher efficiency of Pb 2+ ions adsorption capacity of modified fabric, may be attributed to that, the adsorption of Pb 2+ ions from aqueous solutions could be carried out via chemical or physical bonds.…”

“…Many studies were carried out to remove Pb 2+ ions from wastewater by the adsorption method. Gapusan and Balela [ 32 ] used polyaniline synthesized on hallow kapok fiber to remove Pb 2+ ions and anionic methyl orange dye with a maximum adsorption capacity of 136.75 mg g −1 for methyl orange and 63.60 mg g −1 for Pb 2+ ions. Karthik et al [ 33 ] prepared polyaniline graft modified chitosan for removal Cd 2+ and Pb 2+ ions from aqueous solutions.…”

In this article, phosphorylated cotton fabric was modified with polyaniline using in‐situ chemical solution polymerization to produce conducting fabric. The modified fabric was characterized using Fourier transform infrared spectroscopy (FTIR), X‐ray diffraction (XRD), and scanning electron microscopy (SEM). In addition, the surface electrical resistivity was measured where the modified fabric recorded electrical resistivity of 9.02 kΩ, compared to more than 1000 MΩ for untreated cotton fabrics. The efficiency of the modified fabric in the removal of Pb2+ ions from an aqueous solution was investigated. The phosphorylated cotton fabric modified with polyaniline (C‐Ph‐PANI) exhibited the highest adsorption capacity (250 mg g−1) compared to 54 mg g−1 for the unmodified cotton fabric and 113.7 mg g−1 for cotton fabric modified with polyaniline. The impact of pH, adsorbent amount, adsorbate concentration, and contact time on Pb2+ ions adsorption capacity was also investigated. The adsorption mechanism of Pb2+ ions by C‐Ph‐PANI was studied using Langmuir and Freundlich isotherms. It was found that, the adsorption isotherm obeyed the Langmuir model (monolayer adsorption) with a higher R2 value (0.979) more than the Freundlich model (multilayer adsorption) which recorded a lower R2 value (0.904).
