Highly real nanostructured clay adsorbents of layered double hydroxide (LDH) intercalated with biosafe and
anionic organic diacid was produced at a constant pH with the coprecipitation method. XRD results disclosed
that organic anionic segment is horizontally oriented in the interlayer space, which is obvious from developed
basal spacing of 0.76 to 1.36 nm. Also, a successfully LDH intercalation with examined biosafe diacid was observed
using FT-IR and TGA analysis. Organo-intercalated LDH (I-LDH)/PVC nanocomposites (NCs) with different
content of I-LDH loading were organized through ultrasound irradiation as a green method. The morphological
behaviors and structured properties of achieved NCs were studied by characteristic analyses such as
FT-IR, XRD FE-SEM and TEM. Results of thermal analysis disclosed positive influence of I-LDH on degradation
temperature in compared to the neat PVC, and also residue at 800 °C enhanced from 23 to 42%. The resulting
LDH samples were studied for their performance in removing Cd2+ metal ion from aqueous test solution and the
removal efficiency of these materials at proper pH, different adsorbent mass, Cd2+ concentrations and different
times were documented by atomic adsorption spectrometry. In all samples, with the developed in the adsorbent
mass, the removal efficiency for Cd2+ was improved at the 50 mg/L of metal ion concentration and constant pH
of 7.0. The maximum Cd2+ uptake was 86.17% related to the I-LDH/PVC NC 15 wt%, and also the experimental
data indicated a good compliance with the Langmuir isotherm and pseudo-second-order kinetic model for different
LDH samples.
