“…Moreover, the synthesized nanocomposite was stable and environmentally friendly, with high regeneration capacity and recyclability, and no obvious decrease in capacity even after five cycles. In another study, Fan et al [75] reported the synthesis of a three-dimensional polyaniline graphene oxide PANI/GO material. The prepared material exhibited a loose and spongy macroscale porous structure, with sponges showing a rough and shaggy structure with numerous pores.…”

Heavy metals represent one of the most important kinds of pollutants, causing serious threats to the ecological balance. Thus, their removal from aqueous solution is a major environmental concern worldwide. The process of adsorption—being very simple, economical, and effective—is widely applied for the decontamination of wastewaters from heavy metals. In this process, the adsorbent is the key factor affecting the performance; for this reason, significant efforts have been made to develop highly efficient and selective adsorbents with outstanding properties. This paper presents a detailed overview of the research on different methods of synthesis of nanocomposite materials based on the polymer polyaniline combined with nanomaterials, along with the influence of the synthesis method on their size, morphology, and properties. In addition, the study evaluates the adsorption efficiency of various developed nanocomposites for the adsorption of heavy metals from aqueous solution. From an economical and environmental point of view, the regeneration studies of the nanocomposites are also reported.

“…Influence of pH on the removal of AYR and MB. The pH of solution is an important factor to effect the removal property of composite materials (Fan et al, 2015). The hydrogen ion concentration (pH) primarily affects the degree of ionization of the dyes and the surface properties of the adsorbent.…”

“…Unfortunately, the natural APT mineral is usually low in adsorption capacity and difficult to reuse. Polyaniline (PANI), with linear macromolecule chains, has abounded amine and imine functional groups, which exhibit good adsorption for various pollutants and electrical conductivity (Fan et al., 2015; Xu et al., 2015). Up to now, there are few reports on the utilization of organic conductive polymers to modify the surface of nZVI particles for improving reactivity.…”

In this paper, polyaniline/attapulgite (PANI/APT)-supported nanoscale zero-valent iron (nZVI) composites were synthesized by liquid-phase chemical reduction method and used for the removal of two kinds of dyes. The structure of as-prepared nZVI/PANI/APT was characterized by various test methods. The removal property and degradation mechanism for azo (alizarin yellow R, methyl red, chrome black T, methyl orange) and non-azo (methylene blue, rhodamine B) dyes in aqueous solution were investigated.

The experiment results showed that the removal property of the composite materials on azo dyes is obviously better than that on non-azo dyes. The varying removal efficiencies of dyes depend on the different degradation mechanisms. Azo dyes removal by nZVI/PANI/APT was mainly due to the reductive cleavage of the N ¼ N of nZVI, while non-azo dyes removal mainly contributes to the adsorption of PANI/APT. The study demonstrated that nZVI/PANI/APT has potential applications for the removal of azo dyes from wastewaters.

“…Remediation under visible light irradiation of methyl orange from water was reported using PANImodified-BiOCl photocatalyst [22]. A method was described to prepare a threedimensional PANI/GO material for the isolation of Hg(II) from aqueous solution [23]. A novel polymeric membrane was prepared from polyethersulfone (PES) and self-produced polyaniline/iron (II, III) oxide (PANI/Fe 3 O 4 ) nanoparticles and the results proved that the membrane with 0.1 wt% nanoparticles exhibited the highest removal of Cu(II) ion [24].…”
