چکیده
Bu çalışmada, sulu çözeltilerden Cu2+ iyonlarını uzaklaştırmak amacıyla atık portakal kabuğu (APK) değerlendirildi. Portakal kabuğunun karakterizasyonu, yüzey morfolojisi için taramalı elektron mikroskobu-enerji dağılım spektroskopisi (SEM-EDS) ve fonksiyonel grupları Fourier dönüşümü kızılötesi (FT-IR) ile incelendi. Farklı sıcaklıklarda bulunan kinetik değerler yalancı birinci derece, ikinci Elovich parçacık içi difüzyon modeli denklemlerine uygulanmıştır. Adsorpsiyon sürecini daha iyi anlamak Langmuir, Freundlich, Temkin Dubinin-Radushkevich (D-R) adsorpsiyon izotermlerinin uygulanabilirliği Bakırın uzaklaştırılması dereceden model Langmuir izoterm modelini takip etti. uzaklaştırma kapasitesi 298, 308 318 K'de sırasıyla 7.74, 7.98 8.84 mg/g olarak elde edilmiştir. iyonlarının Gibbs serbest enerjisi (ΔGo), ısısı (ΔHo) entropisi (ΔSo) termodinamik veriler -16.76 kj/mol, 29.43 kj/mol 154.79 j/mol bulundu.
