“…Moreover, the n value greater than 1 showed that the adsorption of Zn(II) onto PAM‐2.5b was favorable. The maximum adsorption capacity was greater than the value of various reported adsorbent for Zn(II) removal (Table ) , indicating that the PAMs in situ thermosynthesized by PDILMs could effectively remove Zn(II) from waste water.…”

This paper reported the in situ fabrication of high‐performance poly(ionic liquid) adsorbents by using polymeric double‐ionic liquid microemulsions (PDILMs)‐mediated thermosynthesis. The PDILMs were successfully formed and their pseudo‐ternary phase diagram was presented. Subsequently, poly(ionic liquid)s were in situ thermosynthesized in PDILMs. The microstructure of the prepared poly(ionic liquid)s was characterized by FTIR, Tg, and DSC analyses. Besides, the influence of various parameters including the crosslinking agent amount, reaction time and adsorbent dosage on the adsorption behavior of poly(ionic liquid)s for Zn(II) was investigated in detail. The results indicated that poly(ionic liquid)s were successfully in situ polymerized within PDILMs, and designed polymers exhibited excellent adsorption property for Zn(II) from aqueous water. Adsorption kinetics and adsorption isotherms further revealed that the adsorption process followed the pseudo‐second‐order kinetic model, and the Freundlich adsorption isotherm models were more suitable for the description of poly(ionic liquid)s for Zn(II) adsorption.

“…In order to achieve sufficient adsorption, 480 min was selected as the optimum contact time. The influence on the adsorption potential of the designed PILs indicated that the maximum adsorption capacity of the PILs for Zn(II) was greater than the values of various reported adsorbents [23,24,25,26,27,28].…”

This paper reports the successful construction of novel polymerizable ionic liquid microemulsions and the in situ synthesis of poly(ionic liquid) adsorbents for the removal of Zn2+ from aqueous solution. Dynamic light-scattering data were used to confirm the polymerization media and to illustrate the effect of the crosslinker dosage on the droplet size of the microemulsion. FTIR and thermal analysis were employed to confirm the successful preparation of the designed polymers and characterize their thermostability and glass transition-temperature value. The optimization of the adsorption process indicates that the initial concentration of Zn2+, pH, adsorbent dosage and contact time affected the adsorption performance of poly(ionic liquid)s toward Zn2+. Furthermore, our research revealed that the adsorption process can be effectively described by the pseudo second-order kinetic model and the Freundlich isotherm model.

“…Among the above-mentioned RSM models, CCD, is one of the most effective experimental designs. This is because CCD allows each independent variable to be investigated at five levels (that is, two-level factorial (±1), axis points (±α) and central points (0) (Mousavi et al, 2018). In addition, in cases where many variables need to be optimized, screening designs such as full or fractional factorial designs are mostly applied (Asadollahzadeh et al, 2014;Benredouane et al, 2016).…”

In this study, a magnetic porphyrin-based porous organic polymer (MP-POP) nanocomposite was successfully synthesized according previous studies and applied as an adsorbent for simultaneous extraction and preconcentration of four neonicotinoid insecticides from surface river water. The MP-POP was characterized using X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy/energy dispersive x-ray spectroscopy (SEM/EDS), N 2-adsorption/desorption analysis, Fourier Transform infrared spectroscopy (FTIR). The neonicotinoid insecticides were quantified using high performance chromatography coupled with diode array detector (HPLC-DAD). The MP-POP shown to have a high surface area, highly porous structure and strong affinity toward the investigated analytes. The adsorption capacities were 99.0, 85.5, 90.0, and 79.4 mg g −1 for acetamiprid, clothiandin, thiacloprid and imidacloprid, respectively. The influential parameters affecting the magmatic µ-solid phase extraction (M-µ-SPE) procedure were investigated using fractional factorial design and surface response methodology (RSM). Under optimum conditions, the method exhibited relatively low limit of detection in the range of 1.3-3.2 ng L −1 , limit of quantification in the range of 4.3-11 ng L −1 and wide linearity (up to 600 µg L −1). The intraday and interday precision, expressed as the relative standard deviation (RSD) were <5%. The percentage recoveries for the four target analytes ranged from 91 to 99.3% for the spiked river water samples. The method was applied for determination of neonicotinoids in river water samples and concentrations ranged from 0 to 190 ng L −1 .
