Özet:

 In this study, a series of adsorption studies were carried out for the concentration range of 18.08 - 183.95 mgL NiII in metal plating industry wastewater using graphene oxide. Under constant stirring speed of 200 rpm, optimum pH6 and optimum contact time was found to be 90 minutes. Temkin isotherm as a pseudo 2nd order kinetic isotherm was chosen as the appropriate model for adsorption kinetics. The optimum amount of graphene oxide as adsorbent was determined as 0.016 mgL and accordingly the maximum adsorption capacity was 112.56 mgg. Considering the literature comparisons; it was concluded that graphene oxide can be used as an improvable adsorbent, however, high efficiency cannot be obtained alone, but high efficiency can be achieved with graphene oxide if it is functionalized.

 Grafen oksit kullanılarak atıksulardan nikelin gideriminin amaçlandığı bu çalışmada, metal kaplama endüstrisi atıksuyundaki 18.08  183.95 mgL NiII konsantrasyon aralığı için bir dizi adsorpsiyon çalışması gerçekleştirilmiştir. 200 rpm sabit karıştırma devri altında optimum pH6 ve optimum temas süresi 90 dakika olarak bulunmuştur. Adsorpsiyonda kinetik olarak; yalancı 2. derece kinetik izoterm olarak Temkin izotermi uygun model olarak seçilmiştir. Adsorbent olarak optimum grafen oksit miktarı 0.016 mgL ve buna bağlı olarak maksimum adsorplama kapasitesi 112.56 mgg belirlenmiştir. Literatür karşılaştırmaları da dikkate alınarak; grafen oksitin geliştirilebilir bir adsorbent olarak kullanılabileceği, bununla birlikte tek başına yüksek verim elde edilemeyeceği ancak fonksiyonelleştirilmesi halinde grafen oksit ile yüksek verim sağlanabileceği sonucuna varılmıştır.
