چکیده
Bu çalışmada, kaliks[4]aren temelli grafen oksit (GO-Epoksi-C[4]CN), öncelikle grafit tozundan Hummers metodu kullanarak oksitin (GO) sentezlenmesi ve (3-glisidoksipropil)trimetoksisilan (GPTMS) ile etkileştirilerek epoksi ucundan p-ter-bütilkaliks[4]aren dinitril türevinin bağlanması elde edildi. Sentezlenen bileşiklerin karakterizasyonları, 1H NMR FTIR analizleri gerçekleştirildi. Elde edilen yeni adsorban atık sulardan p-nitro fenolün (PNF) giderilmesi için kullanıldı. Öncelikle, başlangıç bileşikleri kullanılarak karşılaştırma çalışmaları gerçekleştirildi % 81 adsorpsiyon verimi diğerlerine göre oldukça yüksek bir verim sağladığı gözlendi. Çalışmanın devamında, pH konsantrasyonun adsorpsiyona etkisi incelendi. Konsantrasyon çalışmalarından bulgular ışığında adsorpsiyonun Langmuir izotermiyle daha uyumlu olduğu görüldü.

Efficiency Assesment of Chitosan Graphene Oxide Composite in Aniline Removal from Aqueous Solutions
Background: Aniline is a toxic compound characterized by high solubility in water (3.5 percent; 35000 mg/l) leading to increased presence risk of aniline in wastewater. The presence of this compound in the blood causes the formation of met hemoglobin and prevent oxygen uptake and plays a key role in chemical asphyxiation, moreover, it has been thought as a carcinogenic risk factor to humans...

In this paper, a one-pot and easy-to-handle method at room temperature without additional chemicals for the modification of graphene oxide (GO) with surfactant is found. Removal of nickel (II) ions from aqueous solutions by GO and surfactant (sodium dodecyl sulphate) modified graphene oxide (SDS-GO) was studied spectrophotometrically at room temperature as a function of time, initial concentrat...
متن کاملRemoval of natural organic matter from aqueous solutions by electrocoagulation
Natural organic matter (NOM) affects some qualitative parameters of water such as color. In addition, it can deteriorate the performance of water treatment process including coagulation, adsorption, and membranes. NOM also reacts with chlorine in the chlorination process and may form disinfection by-products. The present study was carried out in laboratory-scale in a batch system using a cylind...

The feasibility of employing nanofiltration (NF) in the decolorization of ionic (direct blue 86) and nonionic (disperse blue 56) dye aqueous solutions was investigated. The effects of feed concentration (60- 180 mg/l), pressure (0.5- 1.1 MPa) and pH (6- 10) were studied. Experiments were performed in a laboratory- scale set up by using a TFC commercial spiral wound polyamide nanofilter. The res...
متن کاملEnhanced adsorptive removal of p-nitrophenol from water by aluminum metal-organic framework/reduced graphene oxide composite.
In this study, the composite of aluminum metal-organic framework MIL-68(Al) and reduced graphene oxide (MA/RG) was synthesized via a one-step solvothermal method, and their performances for p-nitrophenol (PNP) adsorption from aqueous solution were systematically investigated. The introduction of reduced graphene oxide (RG) into MIL-68(Al) (MA) significantly changes the morphologies of the MA an...
