Abstract
Bu çalışmada, kaliks[4]aren temelli grafen oksit (GO-Epoksi-C[4]CN), öncelikle grafit tozundan Hummers metodu kullanarak grafen oksitin (GO) sentezlenmesi ve (3-glisidoksipropil)trimetoksisilan (GPTMS) ile etkileştirilerek epoksi ucundan p-ter-bütilkaliks[4]aren dinitril türevinin bağlanması ile elde edildi. Sentezlenen bileşiklerin karakterizasyonları, 1H NMR ve FTIR analizleri ile gerçekleştirildi. Elde edilen yeni adsorban (GO-Epoksi-C[4]CN), atık sulardan p-nitro fenolün (PNF) giderilmesi için kullanıldı. Öncelikle, adsorban ve başlangıç bileşikleri kullanılarak karşılaştırma çalışmaları gerçekleştirildi ve % 81 adsorpsiyon verimi ile diğerlerine göre oldukça yüksek bir verim sağladığı gözlendi. Çalışmanın devamında, pH ve konsantrasyonun adsorpsiyona etkisi incelendi. Konsantrasyon çalışmalarından elde edilen bulgular ışığında adsorpsiyonun Langmuir izotermiyle daha uyumlu olduğu görüldü.
In this study, calix[4]arene-based graphene oxide (GO-Epoxy-C[4]CN) was synthesized using graphene oxide (GO), which was obtained from graphite powder by the Hummers method. After GO preparation, it was reacted by (3-glycidyloxypropyl)trimethoxysilane (GPTMS) to get its epoxy (GO-Epoxy). Then, GO-Epoxy-C[4]CN was obtained by immobilization of p-tert-butylcalix[4]arene nitrile derivative onto the GO-Epoxy. Characterizations of synthesized compounds were performed by 1H NMR and FTIR analysis. The obtained new adsorbent (GO-Epoxy-C[4]CN) was used for the removal of p-nitrophenol (PNP) from wastewater. First of all, comparison studies were carried out using adsorbent and starting compounds, and it was observed that it provided a very high efficiency with 81% adsorption efficiency compared to the others. Then, the effect of pH and concentration on adsorption was investigated. Hence, it was seen that the adsorption was more compatible with the Langmuir isotherm.
