Abstract

Since copper and lead are the most well-known heavy metals, eggshells were used to remove them from the aqueous solution. In this study, it was used two species; Quail (Coturnix coturnix japonica) and Greylag Goose (Anser anser) and three forms (pure, powdered and calcined forms) of eggshells. Using coupled plasma optical emission spectroscopy (ICP-OES), Fourier-transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) methods, it was investigated whether copper and lead were adsorbed on eggshells; in different species and different forms. According to ICP-OES results, it was observed that calcined eggshells retained more amount of Cu and Pb than uncalcined eggshells. By analyzing the FTIR results, even if the eggshells were in different forms, the characteristic bands of the eggshells were almost seen in samples. After the adsorption process, new bands arose in addition to the characteristic eggshell bands. These new bands are thought to be related to the Cu and Pb loading in the eggshell. With SEM images, it was observed that metal loaded accumulated on the outer surface of the eggshell. This result is also in good agreement with the EDS results.

Özet

Bakır ve kurşun en iyi bilinen ağır metaller olduğundan, bunların sulu çözeltiden uzaklaştırmak için yumurta kabukları kullanıldı. Bu çalışmada iki tür kullanıldı; bıldırcın (Coturnix coturnix japonica) ve boz kaz (Anser anser) ve yumurta kabuğunun üç formunu (saf, toz ve kalsine formlar) kullandık. Eşleştirilmiş plazma optik emisyon spektroskopisi (ICP-OES), Fourier-dönüşümlü kızılötesi (FTIR) spektroskopisi, taramalı elektron mikroskobu (SEM) ve enerji dağılımlı spektroskopi (EDS) yöntemleri kullanılarak, yumurta kabuklarına bakır ve kurşunun adsorbe edilip edilmediği araştırıldı; farklı türlerde ve farklı formlardaki yumurta kabuklarında. ICP-OES sonuçlarına göre, kalsine edilmiş yumurta kabuklarının, kalsine edilmemiş yumurta kabuklarından daha fazla miktarda Cu ve Pb tuttuğu gözlemlenmiştir. FTIR sonuçları analiz edildiğinde, yumurta kabukları farklı formlarda olsa bile, örneklerde yumurta kabuklarının karakteristik bantları hemen hemen aynı bölgelerde görülmüştür. Adsorpsiyon işleminden sonra karakteristik yumurta kabuğu bantlarına ek olarak yeni bantlar ortaya çıkmıştır. Bu yeni bantların yumurta kabuğundaki Cu ve Pb yüklü olmasıyla ilgili olduğu düşünülmektedir. SEM görüntüleri ile yumurta kabuğunun dış yüzeyinde metalin biriktiği gözlenmiştir. Bu sonuç, EDS sonuçlarıyla da iyi bir uyum içindedir.
