“…Figure 8 shows that both PANi and the composite 70%PANi-30%ZnO were more effective than the other materials even at 0.05 g/L (i.e., lowest dosage) with a removal ratio of almost 100%. The treated PANi and the other composites material showed a signi cant increase in the removal of MO with the increase in the adsorbent dose (0.05-0.2 g), similar to previous researchers who reported that Polyaniline and its modi ed forms have been effective adsorbents for the adsorption of dyes and heavy metals [47][48][49][50].…”

Polyaniline PANi/zinc oxide ZnO nanocomposite has been chemically synthesized by using formic acid. ZnO/PANi nanocomposites containing different weight content of ZnO nanoparticles (10, 20, and 30 wt%). ZnO nanoparticles were prepared by co-precipitation method. Characteristics such as structural, morphological and absorption of the prepared nanocomposites were studied by XRD, FTIR, SEM and UV–vis spectra. X-ray diffraction of zinc oxide nanoparticles confirmed formation of hexagonal wurtzite crystalline structure, also the substituted zinc oxide nanoparticles in different percentage to semi-crystalline polyaniline indicating nearly the same crystalline structure of ZnO/PANi nanocomposites. The Fourier Transform Infrared Spectra (FT-IR) of ZnO nanoparticles, PANi and their composites have been analyzed in the frequency range between 400–4000 cm− 1. The characteristic FT-IR peaks of ZnO nanoparticles show shifts to lower wave numbers in all composites. These observed effects may be due to conjugation and some chemical interactions between ZnO nanoparticles and PANI molecular chain. The results confirmed that the PANI successfully grown on surface of ZnO nanoparticles. The ZnO nanoparticles, PANI and ZnO/PANi nanocomposites were further applied to remove methylene orange dye, the effect of pH, initial dye concertation and ZnO nanoparticles dose were investigated via a batch experimental. According to the results, that the hybrid composite of ZnO/PANi increased the photo degradation of methylene orange dye molecules in aqueous solution compared with parent materials. Maximum removal efficiencies at optimum conditions were higher than 97% at pH 11, concentration of dye:10 mg/l, time equal 40 min and dose 0.1 g of PANi/ZnO.

In this study, a novel adsorbent was developed based on nickel oxide, strontium oxide and zirconia oxide and was anchored onto graphene oxide to produce a heterogeneous nanocomposite (NiSr-ZrO 2 /GO) for efficient removal of ammonia from industrial wastewater. The proposed nanocomposite was characterized using FTIR, XRD, SEM, EDX, BET, and TEM techniques. Effects of changing important parameters on the ammonia adsorption such as pH, adsorbent dosage, contact time, and initial concentration of ammonia were investigated. Different models were conducted to study the kinetics and isotherms equilibrium data of the adsorption process. The results revealed that the adsorption kinetics was well-fitted to the second-order model. The equilibrium data were well fitted on Langmuir isotherm model with a maximum monolayer adsorption capacity of 181.81 mg g −1 (R 2 = 0.997). Adding metal-containing species to graphene oxide can favorably interact with ammonia.

“…The use of PANI-clay hybrid materials for the removal of Cu (II) was reported by [37]. Additionally, removal of arsenic (III) ions by magnetic polyaniline doped-strontium titanium nanocomposites adsorbent were reported by [38]. The maximum adsorption capacity was found to be 67.11 mg/g from the Langmuir isotherm model, and the nature of the adsorption process of arsenic (III) ions was found to be exothermic and physisorption deduced from the thermodynamic studies.…”

Proper treatment and disposal of industrial pollutants of all kinds are a global issue that presents significant techno-economical challenges. The presence of pollutants such as heavy metal ions (HMIs) and organic dyes (ODs) in wastewater is considered a significant problem owing to their carcinogenic and toxic nature. Additionally, industrial gaseous pollutants (GPs) are considered to be harmful to human health and may cause various environmental issues such as global warming, acid rain, smog and air pollution, etc. Conductive polymer-based nanomaterials have gained significant interest in recent years, compared with ceramics and metal-based nanomaterials. The objective of this review is to provide detailed insights into different conductive polymers (CPs) and their nanocomposites that are used as adsorbents for environmental remediation applications. The dominant types of CPs that are being used as adsorbent materials include polyaniline (PANI), polypyrrole (Ppy), and polythiophene (PTh). The various adsorption mechanisms proposed for the removal of ODs, HMIs, and other GPs by the different CPs are presented, together with their maximum adsorption capacities, experimental conditions, adsorption, and kinetic models reported.
