The present study reports synthesis and characterization of a new acrylamide‐based monomer containing rhodanine moiety, N‐3‐amino‐thiazolidine‐4‐one‐acrylamide (ATA). Poly(ATA)‐grafted magnetite nanoparticles (poly(ATA)‐g‐MNPs) were prepared using surface‐initiated atom transfer radical polymerization of the monomer on Fe3O4 nanoparticles. The grafted nanoparticles were characterized by Fourier transform infrared analysis, scanning electron microscopy, X‐ray diffraction, and vibrating sample magnetometry. The amount of the grafted polymer was 209 mg g−1, as calculated from thermogravimetric analysis experiment. The capability of poly(ATA)‐g‐MNPs to remove Co(II) cations was shown under optimal conditions of contact time, pH, adsorbent dosage, and initial Co(II) concentration. About 86% of the Co(II) cations were removed over 7 minutes. The adsorption kinetics obeyed the pseudo–second‐order kinetic equation, and the Langmuir isotherm model best described the adsorption isotherm with a maximum adsorption capacity of 3.62 mg g−1. The thermodynamic investigation showed spontaneous nature of the adsorption process (ΔG = −2.90 kJ mol−1 at 25°C ± 1°C). In addition, the poly(ATA)‐g‐MNPs were regenerated by simply washing with an aqueous 0.1M HCl solution. The study of the reusability of the prepared magnetic sorbent revealed that the sorbent can be reused without a significant decrease in the extraction efficiency and be recovered by 95.4% after 7 cycles. These findings suggest that the grafted nanoparticles are stable and reusable adsorbent and can be potentially applied to water treatment in efficient removal of Co(II) cations.

In this research, we synthesized and characterized a new acrylamide‐based monomer containing pyridine and 1,3,4‐oxadiazole moieties, N‐(4‐(5‐(pyridin‐2‐yl)‐1,3,4‐oxadiazol‐2‐yl)phenyl)acrylamide (POPA). Poly(POPA)‐grafted magnetite nanoparticles were then obtained via surface‐initiated atom transfer radical polymerization. The grafted nanoparticles were characterized by Fourier transform infrared analysis, scanning electron microscopy, wide angle X‐ray diffraction, and vibrating sample magnetometry. The amount of the grafted polymer was 126 mg/g, as calculated from thermo gravimetric analysis experiment. The capability of poly(POPA)‐g‐magnetite nanoparticles (MNPs) to remove Co(II) cations, under optimal time period, pH and adsorbent mass, was shown by atomic absorption. The adsorption kinetics obeyed the pseudo–second‐order kinetic equation, and the adsorption isotherm was best described by the Freundlich model with a maximum adsorption capacity of 59.90 mg/g. In addition, the poly(POPA)‐g‐MNPs were regenerated by simply washing with an aqueous 0.1M HCl solution, and no considerable decrease was observed in the extraction efficiency following the test of up to 7 cycles. These findings suggest that poly(POPA)‐g‐MNPs are stable and reusable adsorbent, and they could be potentially applied to water treatments for an efficient removal of Co(II) cations.

ÖZBu çalışmada sulu çözeltilerden Zn(II) iyonlarının piromellitik dianhidrit ile modifiye edilmiş poliamin-poliüre polimeri (PMPPP) üzerine adsorpsiyonu incelenmiştir. Adsorpsiyon çalışmasına etkisi incelenen parametreler; pH, temas süresi, PMPPP dozu, Zn(II) başlangıç konsantrasyonudur. Langmuir ve Freundlich izoterm modelleri kullanılarak analiz edilen Zn(II) adsorpsiyonunun deneysel verileri, tek tabakalı adsorpsiyonu ifade eden Langmuir izotermi ile daha yüksek uyum göstermiştir. Langmuir izotermine göre Zn(II) iyonları için PMPPP'nin maksimum adsorpsiyon kapasitesi 119.1 mg g -1 olarak hesaplanmıştır. PMPPP ile Zn(II) iyonlarının adsorpsiyon kinetiği pseudo ikinci derece modeli ile uyumlu bulunmuştur. Zn(II) adsorpsiyonu için termodinamik hesaplar prosesin ekzotermik ve kendiliğinden gerçekleşme eğiliminde olduğunu göstermiştir.Anahtar Kelimeler: : Zn(II), adsorpsiyon, arıtma, poliamin-poliüre polimeri Adsorption of Zn(II) ıons with polyamine polyurea polymer modified with pyromellitic dianhydride ABSTRACT In this study, adsorption of Zn(II) ions from aqueous solutions was investigated using polyamine polyurea polymer modified with pyromellitic dianhydride (PMPPP). The parameters on the adsorption studies such as pH, contact time, PMPPP dose and initial concentration of Zn(II) were studied. The experimental data analyzed using Langmuir and Freundlich isotherm models were showed a higher compliance with the Langmuir isotherm representing the monolayer adsorption. Maximum adsorption capacity of PMPPP for Zn (II) ions was calculated to be 119.1 mg g -1 according to Langmuir isotherm. Adsorption kinetics of Zn(II) ions on PMPPP were found to consistent with second order model. Thermodynamic calculations showed that the process is exothermic and occurs spontaneously.
