Abstract

The aim of this study is to prepare ion-imprinted polymers which can be used for the selectiveremoval of Cd(II) from synthetic water. Ion-imprinted polymer particles have been prepared bymolecular imprinting technique using 3-mercaptopropyl-trimethoxysilane as monomer,tetraethoxysilane as crosslinking agent in the presence of Cd(II) and dodecylamine. After that, thetemplate ions have been removed using 0.1 M HNO3 /ethanol. A batch procedure has been used for thedetermination of the characteristics of the Cd(II) solid phase. The obtained results have shown that IIPhas a large adsorption capacity (98.2 mgg-1). Optimum pH and adsorption time have found to be 5.0and 2 h, respectively. In selectivity study, it has found that imprinting have been increased affinity ofthe material toward Cd(II) ion over other competitor metal ions with the same charge. The selectivityof Cd(II)/Zn(II), Cd(II)/Cu(II) and Cd(II)/Hg(II) have found to be 2.73, 8.83 and 112 respectivey.

Özet

Bu çalışmanın amacı, sentetik sudan Cd(II)nin seçici uzaklaştırılması için kullanılabilecek iyonbaskılı polimer hazırlamaktır. İyon baskılı polimer partikülleri, dodesilamin ve Cd(II) varlığında,çapraz bağlayıcı olarak teraetoksisilan, monomer olarak 3-merkaptopropil-trimetoksilanın kullanıldığı moleküler baskılama tekniği ile hazırlanmıştır. Daha sonra baskı iyonları 0,1 M HNO3/etanolkullanılarak uzaklaştırılmıştır. Beç işlemi, Cd(II) katı faz özelliklerinin belirlenmesi için kullanılmıştır.Elde edilen sonuçlar, iyon baskılı polimerin büyük adsorpsiyon kapasitesine (98.2 mgg-1) sahipolduğunu göstermiştir. Optimum pH ve adsorpsiyon süresi sırasıyla 5.0 ve 2 saat olarak bulunmuştur.Seçicilik çalışmalarında, baskılama aynı yüklü diğer yarışmacı metal iyonları üzerinden Cd(II)iyonlarına doğru materyalin afinitesinin arttığı bulunmuştur. Cd(II)/Zn(II), Cd(II)/Cu(II) andCd(II)/Hg(II)ın seçicilikleri sırasıyla 2,73; 8,83 ve 112 olarak bulunmuştur.
