“…Various types of chelating resins are well known and widely used in several applications for water and wastewater treatment plants, especially in industrial estates for removing metals selectively via commercially available ion exchange processes. In recent years, different functional groups of chelating resin were widely used for base metal purification and separation [ 1 ] through the ion exchange process, especially for rare earth elements such as Amberlite XAD-4 (styrene divinyl benzene copolymer) [ 2 ], Dowex-M4195 and Dow-4196 (bis-picolylamine) [ 3 ], Lewatit TP 207 and SIR-300 (iminodiacetate) [ 4 , 5 ], SIR-500 (amino phosphonic) and Dowex XUS43605 (hydroxypropylpicolylamine) [ 6 , 7 ]. These chelating resins were applied for extraction of various metals such as Pb(II)/lead, Cu(II)/copper, Cd(II)/cadmium, Zn(II)/zinc, La(III)/lanthanum, Ni(II)/nickel, Cr(III, IV)/chromium, Fe(II)/iron and Co(II)/cobalt ions [ 8 , 9 ] from aqueous solutions and especially in electronics waste applications at a low pH.…”

Advanced technologies of electronics industries have led to environmental contamination concerns, especially waste print circuit boards containing a very high concentration of copper (II) ions, which can be discharged in wastewater containing many contaminated metals. A low pH is a necessity for treating industrial wastewater containing heavy metals to meet engineering process design. A novel polymeric bispicolamine chelating resin, Dowex-M4195, was applied as an alternative for investigating the behavior of copper (II) in acidic solution via an ion exchange method in a batch experiment system. Characterization of physical and chemical properties before and after ion exchange were also explored through BET, SEM-EDX, FTIR and XRD. Response surface methodology was also applied for optimization of copper (II) removal capacity using design of experiment for selective chelating resin at a low pH. The results indicate that H+ Dowex-M4195 chelating resin had a high-carbon content and specific surface area of >64% and 26.5060 m2/g, respectively. It was predominantly macropore porous in nature due to the N2 gas adsorption isotherm and exhibited type IV with insignificant desorption hysteresis loop of H1-type. It was spherical and cylindrical. After the ion exchange process of copper (II)-loaded H+ Dowex-M4195, the specific surface area and total pore volume decreased by about 17.82% and 5.39%, respectively, as compared to H+ Dowex-M4195. Hysteresis loop, isotherm and pore size distribution were also similar. Regarding the functional group, the surface morphology and crystalline structures of H+ Dowex-M4195 showed copper (II) compound based on the structure of chelating resin that confirmed effective ion exchange behavior. The design of optimization indicated that copper (II) removal capacity of about 31.33 mg/g was achieved, which could be obtained at 6.96 h, pH of 2 (a desirable low pH), dose of 124.13 mg and concentration of 525.15 mg/L. The study indicated that the H+ Dowex-M4195 (which is commercially available on the market) can successfully be applied as an alternative precursor through the ion exchange method for further reuse and regeneration of the copper (II) in the electronic waste industries and other wastewater applications needed to respond the policy of biocircular green economy in Thailand.

“…Finding the best correlation for equilibrium curve was for optimizing the adsorption system. The Langmuir model is based on the following assumptions:① the adsorbate is adsorbed on the surface of the adsorbent as a monolayer; ② Adsorption is dynamic, and the adsorbed molecules will return to the original solution under the influence of thermal motion; ③ There is no interaction between the adsorbate molecules adsorbed on the surface of the adsorbent ( Vinco et al, 2022 ). The following formula was used to calculate the equilibrium absorption capcity:

where q e was the equilibrium adsorption capacity, mg g −1 ; q m was the maximum adsorption capacity, mg g −1 ; K L was adsorption equilibrium constant, L mg −1 ; C e was the equilibrium adsorption concentration, mg L −1 .…”

1,5-Pentanediamine hydrochloride (PDAH) was an important raw material for the preparation of bio-based pentamethylene diisocyanate (PDI). PDI has shown excellent properties in the application of adhesives and thermosetting polyurethane. In this study, PDAH was recovered from 1,5-pentanediamine (PDA) fermentation broth using a cation exchange resin and purified by crystallization. D152 was selected as the most suitable resin for purifying PDAH. The effects of solution pH, initial temperature, concentration of PDA, and adsorption time were studied by the static adsorption method. The equilibrium adsorption data were well fitted to Langmiur, Freundlich, and Temkin-Pyzhev adsorption isotherms. The adsorption free energy, enthalpy, and entropy were calculated. The experimental data were well described by the pseudo first-order kinetics model. The dynamic experiment in the fixed bed column showed that under optimal conditions, the adsorption capacity reached 96.45 mg g−1, and the recovery proportion of the effective section reached 80.16%. In addition, the crystallization of the PDAH solution obtained by elution proved that the crystal product quality of resin eluting solution was highest. Thus, our research will contribute to the industrial scale-up of the separation of PDAH.
