Moreover, the regeneration efficiency of PANI-ZrWPO 4 was studied, and it was found to be able to remove around 80% of Cr(VI) even after five cycles, demonstrating its potential as an effective and reusable adsorbent.Ībbasian M, Niroomand P, Jaymand M (2017) Cellulose/polyaniline derivatives nanocomposites: synthesis and their performance in removal of anionic dyes from simulated industrial effluents. The XPS spectra confirmed simultaneously adsorption reduction occurs Cr(VI) to Cr(III) through in situ chemical reduction. The removal of Cr(VI) was optimized with the six variables namely adsorbent dose, initial concentration, Time, pH, Temperature, and stirring rate using the Box-Behnken design (BBD) model. ![]() The maximum Langmuir adsorption capacity of PANI-ZrWPO 4 was found to be 71.4 mg g −1. Further investigation was done on the efficiency of the PANI-ZrWPO 4 nanocomposite as an adsorbent for Cr(VI) removal through batch adsorption experiments. The TEM and FESEM images revealed that polyaniline had formed on the exterior of the PANI-ZrWPO 4 nanocomposite. The XRD data showed that the composite had a crystalline nature. The results of the FTIR and Raman spectra confirmed that the conducting PANI polymer interacted with ZrWPO 4 to form the PANI-ZrWPO 4 nanocomposite. The synthesized nanocomposite was characterized by using FESEM, EDX, TEM, XRD, FTIR, Raman, TGA-DTA, XPS, and N 2 adsorption–desorption analysis and chemical analysis to know about the formation of material. A novel polyaniline zirconium tungstophosphate (PANI-ZrWPO 4) nanocomposite was successfully synthesized through an in situ oxidative polymerization reaction followed by a microwave irradiation process.
