“…In general, the adsorption process shall be investigated in both kinetic and thermodynamic studies [84,98]. The kinetic study revealed how fast an adsorption process occurs at a certain operation condition [140].…”

“…A negative change in Gibbs energy denotes a favorable adsorption process at a certain temperature. A positive value of change in enthalpy reflects an endothermic process while a negative value of change in enthalpy reflects an exothermic process [84]. The physisorption process is indicated by the change in enthalpy value less than 20 kJ mol −1 while the chemisorption process is indicated by the change in enthalpy value higher than 20 kJ mol −1 .…”

“…Modification of Amberlite XAD-4 resin with calix[4]arene 9 for As(III) removal from real samples has been evaluated [84]. The calix [4]arene 9 was immobilized on the Amberlite XAD-4 by the stirring method for 120 h in ethanol solvent at room temperature.…”

“…The favorable adsorption was reflected from the negative ΔG o energy (−9.85 kJ mol −1 ) demonstrating that the chemisorption occurred through electrostatic interactions. When the Amberlite XAD-4-calix [4]arene 9 material was employed for a real application, as much as 76% of As(III) could be adsorbed from the Iranian wastewater sample, which is remarkable [84]. On the other hand, the evaluation of As(III) and As(V) adsorption using Merrifield-calix [4]arene 10 resin material has been conducted [113].…”

Water pollutants, i.e., heavy metal ions, pesticides, dyes, and pigments, are contaminating our aquatic environment and generating serious health damage for the human body. Adsorption using ion-exchange resin materials is one of the versatile techniques for water treatment due to its simple and low-cost process. However, when the separation and pre-concentration of the water pollutants only rely on the ion-exchange mechanism, selective removal of water pollutants cannot be easily achieved. In contrast, a supramolecular organic compound named calixarene offers a promising technology for selective ion and molecular discrimination due to strict host-guest interactions. We reviewed the up-to-date research of supramolecular ionexchange resins based on calixarene derivatives for pollutant removal from aquatic environmental samples. There are three techniques to prepare the supramolecular ion-exchange resins based on calixarene derivatives: (1) impregnation of calixarene on the commercially available resins, (2) polymerization of calixarene, and (3) crosslink-reaction of the calixarene derivatives. The description, advantages, and disadvantages of each technique are discussed. By using these techniques, hundreds of ion-exchange resin materials have been successfully prepared and they showed a remarkable capability and selectivity for heavy metal ions, pesticides, dyes, and pigments removal.
