“…In this study, the better applicability of the pseudo-second-order model compared with the pseudo-first-order model for the description of the removal process was observed for halloysite nanoclay. In other studies, it was also used for the removal of oxytetracycline antibiotic [45], methylene blue dye [46,47], Orange G dye [48], lead (II) [49], phosphate [50], and nitrate ions [51]. This indicates that the removal process depends on both the heavy metal ions concentration as well as the number of active sites available on the HS nanoclay.…”

Halloysite (HS) nanoclay was used for the environmental treatment of desalination brine water discharge via the adsorptive removal of selected heavy metals ions; zinc, iron, nickel, and copper, as well as salinity. Different techniques were used for the characterization of the HS nanoclay and it was found that HS nanoclay exists as transparent hollow nanotubes with high surface area. The study showed that most of the heavy metal ions could be removed successfully using the HS nanoclay in a few minutes, at normal conditions. The adsorptive removal of zinc, iron, nickel, and copper, as well as salinity on HS nanoclay was explored kinetically. It was concluded that the pseudo-second-order kinetic model was able to describe the remediation process. In addition, it was found that most of the heavy metals and salinity were removed from the desalination plant outfall brine discharge and the final concentrations were lower than those in the control and standard samples.

“…Due to its versatile properties, such as high surface area, high hydrophilicity, tunable structure by the chemical modification, economic tubular raw material compared to its alternatives, it has been an attractive material to employ in various researches [13,19]. Although there have been a lot of studies regarding the conductive polymer/halloysite composites in the form of nanotubular structure [6,9,12,13,[20][21][22][23][24][25][26][27], to our knowledge, no study has been published for the fabrication of POT/halloysite composite in the literature. Most of these articles contain only the preparation of polyaniline/halloysite composites without investigating the imparted properties of the components.…”

This study outlines the production of an electrically conductive clay-based composite containing the halloysite as clay mineral and poly(o-toluidine) (POT) as a conductive filler. In the study, conductive POT/halloysite composite was obtained by in situ oxidative polymerization of o-toluidine using ammonium persulphate (APS) as an oxidant between the halloysite layers. By changing the polymerization conditions such as polymerization time, o-toluidine concentration, APS, and the concentration of HCl solution used as the reaction medium, the composite with the highest conductivity (7.5×10 -5 S.cm -1 ) was obtained. Structural and morphological changes and thermal behaviors that occurred after the composite formation was revealed using various characterization techniques such as FTIR, XRD, TGA, and SEM. The usability of the prepared POT/halloysite composite as humidity sensing material was tested in comparison with the pure POT component of the composite at a relative humidity (% RH) varied between 41-94 (%). Accordingly, it was found that the composite exhibited a fairly regular resistance change to varying relative humidity compared to pure POT polymer.
