“…Industrial processes usually generate waste materials that if not disposed of properly according to standard conditions of waste disposal, may be harmful to human health [ 1 ]. Disposal of dyes in factory-made liquids into drinking water is a prominent issue because in several places such materials are of high defiance to chemical, biological, or photochemical depravity [ 2 , 3 ]. Dyes are utilized in abundance in many industrial productions, containing textile, leather, cosmetics, cardboard, printing, pharmaceuticals, treated compounds, edible material, etc.…”

Crystals of malachite green (MG), being water-soluble, are effective agents applied to combat fungal and parasitic infections in fish. This study was conducted to evaluate the adsorption of MG as a cationic dye by polymeric resin Amberlyst 15. Changes in several parameters were observed, including the concentration of MG, pH, the adsorption rate and extent, and the temperature that might all affect the efficiency of adsorption. The adsorption method was described well by both the Redlich–Peterson and Langmuir isotherms with R2 of 0.9933 and 0.9880, respectively. The kinetic information is consistent with the Freundlich isotherm model and pseudo-2nd-order kinetics model. Analysis of malachite green was executed by HPLC containing a Eurospher 100-5 C18 (25 cm × 4.5 mm, size of particle 5 μm) column, UV detector was set at 618 nm, and 125 mM ammonium acetate was adapted to pH 4.5 with formic acid-acetonitrile (45 : 55, v/v) as the moving phase. The limit of the discovery factor was 0.02 μgL. The negative value of ΔG° reveals the spontaneity of the absorption method. The positive value of ΔS° (333.1253 J/K mol) gives back randomness at the solid-liquid interface of sorption. The required adsorbent concentration was calculated for removing MG up to an extraction efficiency of 98.27% after 240 minutes.

“…The q max value of methyl violet adsorption using calix [4]arene-resin material (1.25 mol g −1 ) was bigger than the other adsorbents such as activated carbon (3.7 × 10 -6 mol g −1 ), carbon nanotubes (1.1 × 10 -4 mol g −1 ), and wood sawdust (1.2 × 10 -5 mol g −1 ) [99,91]. The q max value for methyl green adsorption using calix [4]arene-resin material (1.04 mol g −1 ) was higher than activated carbon (1.0 × 10 -5 mol g −1 ), and NiFe 2 O 4 -carbon nanotubes (2.4 × 10 -6 mol g −1 ) [45,11]. Meanwhile, the q max value of methylene blue adsorption using calix [4]arene-resin material (0.89 mol g −1 ) was higher than activated carbon (3.7 × 10 -6 mol g −1 ), and the unmodified resin adsorbent (6.0 × 10 -6 mol g −1 ) [150,116].…”

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.

“…Adsorption techniques have potential for removing organics from wastewater due to their high efficiency and ability to separate a wide range of chemical compounds (Adibmehr and Faghihian, 2018; Mittal et al., 2016; Petkovic et al., 2019). The ordinary used adsorbents are activated carbon, molecular sieves, metal organic frameworks, and other adsorbent materials (Dos Reis et al., 2011). The adsorption method has the characteristics of good adsorption capacity, simple operation, and wide application range which has been widely used in the practical work of dye wastewater pollution control.…”

The adsorption of Rhodamine B onto CT269DR resin has been studied through static and dynamic experiments. The effects of shaking speed, resin dosage, and pH on adsorption were investigated by static experiments. The external mass transfer rate remains substantially unchanged when the shaking speed exceeds 160 r min−1. The optimal pH range is 5–8, and an increase of resin dosage can directly improve the percentage of removal of Rhodamine B. The equilibrium isotherm data of Rhodamine B on CT269DR resin fit the Langmuir adsorption isotherm well. The thermodynamics parameters, Δ H = 69.93 kJ mol−1, Δ S = 326.73 J mol−1 K−1, and Δ G < 0, demonstrate that the adsorption of Rhodamine B onto CT269DR resin is spontaneous and endothermic. The pseudo first-order kinetic model can be successfully used to represent the adsorption process and the activation energy is 25.7 kJ mol−1. The dynamic experiments show that the breakthrough point is advanced when the flow rate increases and the bed adsorption capacity increases with increasing temperature. Furthermore, the desorption using the solution of 2% NaOH is suitable for desorption and reusing process, and scanning electron microscope (SEM) and fourier transform infrared spectroscopy (FT-IR) analysis reveals that used resin has good wear resistance and chemical stability. The results confirm that CT269DR resin can be employed as an efficient adsorbent for the removal of Rhodamine B from wastewater.
