Polianilin/Şeker Pancarı Posası (PANI/SBP) Kompoziti Kullanılarak Sulu Ortamdan Nikel ve Bakırın Uzaklaştırılması

Bu çalışmada polianilin/şeker pancarı posası (PANI/SBP) kompozitleri sentezlenmiş ve atık sudan bakır ve nikelin uzaklaştırılmasında kompozitlerin potansiyel kullanımı araştırılmıştır. Kompozitlerin yapısal ve morfolojik özellikleri sırasıyla Fourier Dönüşümü Kızılötesi Spektroskopisi (FTIR) ve Taramalı Elektron Mikroskobu (SEM) ile incelenmiştir. Sulu çözeltilerden metal uzaklaştırma çalışmaları Ultraviyole Görünür Absorpsiyon Spektrometresi (UV-Vis) ile izlenmiştir. Bu aşamada adsorban dozajı, karıştırma hızı ve karıştırma süresi, metal çözeltilerin başlangıç konsantrasyonu ve pH gibi bazı parametreler değiştirilerek metal uzaklaştırma için optimum koşullar belirlenmiştir. Atık sudan metal uzaklaştırma çalışmaları, Endüktif Olarak Eşleştirilmiş Plazma Optik Emisyon Spektrometresi (ICPOES) ile optimum koşullarda gerçekleştirilmiştir. FTIR ve SEM sonuçları, PANI/SBP kompozitlerinin oluşumunu desteklemektedir. Optimum koşullarda, PANI/SBP kompoziti ile muamele edilmiş atık su için elde edilen ICP-OES sonuçları, kompozitin atık sudan bakır ve nikelin uzaklaştırılmasında kullanılabileceğini göstermiştir.

Nickel and Copper Removal from Aqueous Media using Polyaniline/Sugar Beet Pulp (PANI/SBP) Composite

In this study, polyaniline/sugar beet pulp (PANI/SBP) composites were synthesized, and the potential use ofcomposites was determined for the removal of copper [Cu (II)] and nickel [Ni (II)] from wastewater. The structural andmorphological properties of composites were determined by Fourier Transform Infrared Spectroscopy (FTIR) andScanning Electron Microscope (SEM), respectively. The metal removal of composites from aqueous solutions wasmonitored by Ultraviolet Visible Absorption Spectrometer (UV-Vis). At this stage, some parameters, such asadsorbent dosage, stirring speed and contact time, the initial concentration of metal solutions and pH, were changed,and the most suitable condition was selected for metal removal. Metal removal from wastewater was determined byInductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) at optimum conditions. FTIR and SEM resultssupported the formation of PANI/SBP composites. Under optimum conditions, ICP-OES results for wastewater treatedwith PANI/SBP composite showed that this composite can be used for the removal of copper and nickel fromwastewater.
