“…Also, the calculated IB values for MMIP and MNIP are −0.13 and −0.31, respectively, indicating that the effect of liquid film diffusion on the adsorption rate dominates in the whole adsorption process. Most adsorbates are adsorbed from the outer surface after passing the liquid film on the surface of the adsorbents [39] …”

Amoxicillin (AMX) is an antibiotic commonly used to treat bacterial and respiratory diseases in humans and animals. In this study, magnetically imprinted polymers (MMIPs) were successfully synthesized and characterized by the surface imprinting method to selectively separate AMX from an aqueous medium. The suitability of kinetic models and isothermal models for the adsorption of AMX from aqueous solutions using magnetic polymers was compared with an unprinted reference polymer (MNIP). The obtained data showed that the adsorption process is compatible with the pseudo‐second order kinetic model and Langmuir isotherm. In addition, adsorption selectivity experiments were performed and it was found that the MMIPs exhibited excellent selective adsorption capacity for AMX. The MMIPs possessed an adsorption capacity of 134 mg/g for AMX and the imprinting factor was 2.23. The MMIPs were also recyclable and retained 86 % of their adsorption capacity after 7 cycles. Based on these results, the study provides a sustainable option in terms of high added value, environmentally friendly, flexible, safe, energy efficient and cost effective in terms of effective removal of pollutants and recycling of adsorbents.

“…Compared with the other methods, the adsorption method has the advantages of simple process design and operation, low separation cost, good separation performance, and less secondary pollution to the environment. , Therefore, various new adsorption materials, such as organic–inorganic hybrid materials, have been developed based on the adsorption method. Metal–organic frameworks (MOFs) are crystalline porous materials composed of metal ions and organic ligands connected through coordination reactions, which have both the rigidity of inorganic materials and the flexibility of organic materials . Moreover, MOFs have been gradually used in a wide range of fields including gas storage, catalysis, drug release, sensing, and adsorption separation attributed to their high specific surface area, good chemical stability, and excellent thermal stability. − …”

Long-lived radionuclides such as 60Co and 54Mn in radioactive waste water must be properly treated to protect the environment from long-term radioactive hazard. In this study, nine zeolite imidazole frameworks (ZIFs) were initially synthesized to investigate an effective adsorbent for Co(II) and Mn(II) in solution. Zeolite imidazole framework-14 (ZIF-14) with good performance was selected, and subsequent characterization and adsorption performance tests were conducted. The results show that ZIF-14 has good hydrothermal stability within 520 °C. Under the conditions of pH = 6.72, T = 303 K and the initial concentration of 500 mg·L–1, the saturated adsorption capacity for Co(II) and Mn(II) reached 148.55 mg·g–1 and 252.85 mg·g–1, respectively. The analysis of thermodynamic parameters shows that the adsorption process of ZIF-14 to Co(II) and Mn(II) is spontaneous and endothermic. The pseudo-second-order kinetic model, Langmuir isotherm model, and Boyd model are more in line with the adsorption process of Co(II) and Mn(II) by ZIF-14, which proves that the active sites on the surface of ZIF-14 are evenly distributed, and the adsorption process is single-molecule chemical layer adsorption. In addition, the liquid film diffusion dominates the adsorption rate during the adsorption process of Co(II) and Mn(II) by ZIF-14. ZIF-14 has good selectivity for cobalt and manganese in both high-concentration interference ion solution and multimetal ion solution with the same concentration. Moreover, ZIF-14 still has good adsorption performance after five times of elution.
