Bu çalışmada şelatlaşma fonksiyonu olan poliamin-poliüre reçinesi sentezlenmiş ve kesikli sistemle sulu çözeltilerden Cu(II) iyonlarının adsorpsiyonla gideriminde kullanılmıştır. Adsorpsiyona pH değişimi, adsorbanın dozu, karıştırma süresi ve başlangıç derişiminin etkisi incelenmiştir. Ayrıca deney sonuçlarının Langmiur ve Freundlich denge eşitliklerine uygunluğu araştırılmıştır. Yapılan çalışmalar sonucunda optimum pH:6,0, uygun reçine dozu 0,3 g/100 mL çözelti, karıştırma süresi 60 dakika olarak belirlenmiştir. Deney verilerinin Langmuir ve Freundlich denge eşitliklerine uygulanması sonucunda, adsorpsiyonun kemisorpsiyonu açıklayan Langmuir denge eşitliğine 0,998 regresyon katsayısıyla uyduğu görülmüştür. Maksimum adsorpsiyon kapasitesi 52,356 mg/g olarak bulunmuştur. Sonuçlar sentezlenen reçinenin yüksek adsorpsiyon kapasitesine sahip olduğunu göstermektedir.

Anahtar Kelimeler
