Synthesis, Characterization and Adsorption of Bisphenol A Using Novel Hybrid Materiel Produced from PANI Matrix Reinforced by Kieselguhr

Abstract

This study investigated the preparation of new adsorbent based PANI and Kieselguhr (KG). The produced materials were characterized by XRD, XPS, TEM, FTIR, TGA and BET. Thereby, hybrid material PANI@KG highest SBET values (about 47.82 m2.g−1). The adsorption capacity of the PANI, KG and PANI@KG were tested on BPA ions from aqueous solutions at ambient temperature and pH 6.0, the maximum capacity of adsorption was observed to be 63.68 mg.g−1 which is obtained from Langmuir adsorption isotherm by hybrid adsorbent PANI@KG. Besides, the pseudo-2nd order kinetics was more consistent with the obtained experimental data. Furthermore, the hybrid material possessed highest adsorption capacity after six cycles of adsorption-desorption process. Moreover above 80% of removal percentage was obtained even after three recycles. Hence we expect that this organic-inorganic adsorbent can be selected as a potential candidate for water treatment.

A deep learning neural network approach for predicting the factors influencing heavy-metal adsorption by clay minerals

“…In addition, numerous synthetic adsorbents have been developed to remove heavy-metal toxins and organic pollutants from wastewater (Dai et al , 2021; Wang et al , 2022). Examples of these include the hybrid polyaniline matrix reinforced by kieselguhr (PANI@KG) adsorbent for water treatment (Ouis et al , 2022) and activated carbon based on prickly pear seeds and a conductive polymer matrix based on polyaniline for the removal of anionic Congo red dye from aqueous solutions (Lahreche et al , 2022). However, different minerals exhibit varying adsorption rates for the same heavy metal (Adebowale et al , 2006).…”
