“…The literature review indicates that SIRs are efficiently employed for the extraction of metal ions with well stability during several adsorption–desorption cycles 52 . In present work also, the used Amberlite XAD-7 resin impregnated via D2EHPA extractant was recovered 3 times and showed high stability during 3 adsorption–desorption cycles.…”

In this paper, the removal efficiency of Cerium (Ce(ΙΙΙ)) and lanthanum (La(ΙΙΙ)) ions from aqueous solution using Amberlite XAD-7 resin impregnated with DEHPA(XAD7-DEHPA) was studied in the batch system. The adsorbent ( XAD7–DEHPA) was characterized by SEM–EDX, FTIR and BET analysis Techniques. The response surface methodology based on the central composite design was applied to model and optimize the removal process and evaluate operating parameters like adsorbent dose (0.05–0.065), initial pH (2–6) and temperature (15–55). Variance analysis showed that the adsorbent dose, pH and temperature were the most effective parameters in the adsorption of Ce(ΙIΙ)and La(IΙI) respectively. The results showed that the optimum adsorption condition was achieved at pH = 6, the optimum amount of absorbent and the equilibrium time equal to 0.6 gr and 180 min, respectively. According to the results, the adsorption percentage of Ce(ΙIΙ) and La(ΙΙΙ) ions onto the aforementioned resin were 99.99% and 78.76% respectively. Langmuir, Freundlich, Temkin and sips isotherm models were applied to describe the equilibrium data. From the results, Langmuir isotherm (R2 (Ce) = 0.999, R2 (La) = 0.998) was found to better correlate the experimental rate data. The maximum adsorption capacity of the adsorbent ( XAD7–DEHPA) for both Ce(IΙI) and La(III) was found to be 8.28 and 5.52 mg g−1 respectively. The kinetic data were fitted to pseudo-first-order, pseudo-second-order and Intra particle diffusion models. Based on the results, the pseudo-first-order model and Intra particle diffusion model described the experimental data as well. In general, the results showed that ( XAD7–DEHPA) resin is an effective adsorbent for the removal of Ce(IΙI) and La(III) ions from aqueous solutions due to its high ability to selectively remove these metals as well as its reusability.

“…The resin is widely employed for removing organic pollutants, such as aromatic hydrocarbons [73], pesticides [74], oil [75], and pharmaceutical residues [72], from wastewater and contaminated soils. Moreover, The amberlite XAD-7 could be modified with specific reagents to enhance the removal of metal ions in environmental samples including Ce (III) and La (III) [76], Cr (VI) [77], and Ni (II) [78]. It has been reported that Congo red modified Amberlite XAD-7 resin was used for the preconcentration and determination of trace metals in fish using flame atomic absorption spectrometry [79].…”

Novel approaches were developed for the colorimetric detection of norfloxacin and ceftazidime using chemically modified polymer resin and cotton sponge as sensing materials, respectively. For norfloxacin detection, the optimum condition was achieved by using a resin modified with 6.0 ?M Congo red at pH 6 to extract norfloxacin in 10 mL of�sample at pH 2. The reaction was completed within 15 minutes. Regarding ceftazidime detection, a cotton sponge functionalized with polyethyleneimine (PEI) was fabricated and characterized by FTIR, SEM, and ninhydrin test. To fabricate the PEI-sponge, 170 mM 3-aminopropyl triethoxysilane (APTES) was used to modify 1.0 g cotton fibers and 210 ?M PEI for grafting on 0.5 g of APTES-sponges. The colorimetric detection of ceftazidime based on the azo dye formation on the sponge surface was achieved by using a reagent mixture containing 0.5 M HCl, 30 mM NaNO2, and 25 ?M chromotropic acid. Under optimized conditions, the methods provide a linear range from 0 1.5 mg L-1 and 0.5 3.0 mg L-1 for norfloxacin and ceftazidime determination, respectively. The limit of detection of norfloxacin and ceftazidime was found to be 0.23 mg L-1 and 0.06 mg L-1, respectively. The methods were applied to detect norfloxacin and ceftazidime in spiked water samples with recoveries ranging from 90 106% and 83 103%, respectively, and % RSD lower than 10.53%.
