Abstract
Bu çalışmanın amacı, grafen bazlı hibrit bir malzemenin katı faz ekstraksiyon işleminde diğer maddeleri çekebilen ve ayırabilen bir madde olarak kullanılmasının etkinliğini değerlendirmektir. Amaç, Pb(II) ve Hg(II) metal iyonlarının insan sağlığı ve çevre üzerindeki potansiyel olumsuz etkilerini azaltmaktır. Grafen oksit, güçlü oksitleyicilerin kullanımını içeren ilk aşamada Hummers prosesi kullanılarak grafit üzerinde üretilmiştir. Daha sonra, GO silanize etmek için 3-(trimetoksisilen)propilamin ile muamele edilmiştir. Daha sonra silanize edilmiş GO, grafen-oksit-Schiff baz malzemesini oluşturmak için 3,5-dikloro-salisilaldehit ile birleştirildi. Bileşiklerin yapısı sentezin her aşamasında UV-Vis spektroskopisi, Fourier dönüşümlü kızılötesi spektroskopisi, X-ışını kırınımı, taramalı elektron mikroskopisi, transmisyon elektron mikroskopisi, termogravimetrik analiz ve enerji dağılımlı X-ışını spektroskopisi gibi bir dizi analitik teknik kullanılarak belirlendi. Çalışmada pH, sıcaklık, temas süresi ve diğer malzeme özelliklerinin adsorpsiyon üzerindeki etkisi araştırılmıştır. Çalışma, grafen bazlı hibrit malzemenin hem atık hem de içme suyundan ağır metal iyonlarını adsorbe etmede oldukça verimli olduğunu göstermiştir. Bu durum, ağır metal kirleticileri etkili bir şekilde uzaklaştırabildiği için grafenin çevresel uygulamalardaki potansiyelini göstermektedir.

Abstract
The objective of this study is to evaluate the effectiveness of using a graphene-based hybrid material as a substance that can attract and separate other substances in a solid-phase extraction process. The goal is to reduce the potential adverse effects of Pb(II) and Hg(II) metal ions on human health and the environment. Graphene oxide was produced on graphite using the Hummers process during the early phase, which involved the use of potent oxidizers. Afterwards, graphene oxide (GO) was treated with 3-(trimethoxycylene)propylamine to silanize it. Then, the silanized GO was combined with 3,5-dichloro-salisylaldehyde to create the graphen-Schiff base material. The structure of the compounds was determined at each stage of synthesis using a range of analytical techniques, such as UV-Vis spectroscopy, Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, transmission electron microscopy, thermogravimetric analysis, and energy dispersive X-ray spectroscopy. The study investigated the influence of pH, temperature, contact time, and other material characteristics on adsorption. The study demonstrated that the graphene-based hybrid material is highly efficient at adsorbing heavy metal ions from both waste and drinking water. This demonstrates the potential of graphene in environmental applications, as it can effectively remove heavy metal contaminants.
