Heavy Metal Removal with ZnO-Chitosan Composite

Öz

In the study, ZnO particles were synthesized by green synthesis using Allium cepa (A. cepa) shells and the Nickel (II) (Ni (II)) removal potential of the ZnO-Ch composite formed with chitosan (Ch) was investigated. Characterization of the synthesized ZnO-Ch composite was performed by scanning electron microscopy (SEM), Fourier transform infrared (FTIR) and X-ray diffraction (XRD). In the study, pH (2,0-6,0), temperature (25-55 oC), amount of adsorbent (0,,25-1,0 g/L), contact time for Ni (II) adsorption in batch system with ZnO-Ch composite. (15-1440 min) and initial pollutant concentration (20-300 mg/L) were examined and optimum removal conditions were investigated. The optimum conditions obtained were determined as pH 5,0, temperature 25 0C, amount of adsorbent 0,5 g/L, contact time 300 minutes (min). The maximum adsorption capacity of the composite in Ni (II) removal was calculated as 222,22 mg/g according to the Langmuir isotherm model. In temperature studies, the decrease in adsorption capacity with increasing temperature showed that the system was exothermic.

ZnO-Kitosan Kompoziti ile Ağır Metal Giderimi

Öz

Çalışmada Allium cepa (A. cepa) kabukları kullanılarak yeşil sentez ile ZnO partikülleri sentezlendi ve kitosan (Ch) ile oluşturulan ZnO- Ch kompozitin Nikel (II) (Ni (II)) giderim potansiyeli incelendi. Sentezlenen ZnO-Ch kompozitin taramalı elektron mikroskopisi (SEM), Fourier transform infrared (FTIR) ve X-ışını difraksiyonu (XRD) ile karakterizasyonu gerçekleştirildi. Çalışmada ZnO-Ch kompoziti ile kesikli sistemde Ni (II) adsorpsiyonu için pH (2,0-6,0), sıcaklık (25-55 oC), adsorban miktarı (0,25-1,0 g/L),temas süresi (15-1440 dk) ve başlangıç kirletici derişimi (20-300 mg/L) incelenerek optimum giderim koşulları incelenmiştir. Elde edilen optium koşullar pH 5,0, sıcaklık 25 0C, adsorban miktarı 0,5 g/L, temas süresi 300 dakika (dk) olarak belirlenmiştir. Ni (II) gideriminde kompozitin maksimum adsorpsiyon kapasitesi Langmuir izoterm modeline göre 222,22 mg/g olarak hesaplandı. Yapılan sıcaklık çalışmalarında artan sıcaklık ile adsorpsiyon kapasitesinin düşmesi sistemin ekzotermik olduğunu gösterdi.
