Abstract

In this work, cobalt(II/III) oxide (Co3O4) nano/microflowers were practically synthesized in laboratory conditions. Adsorbence properties of the nanoflowers were investigated for the removal of cadmium and chromium heavy metal ions. To assess the chemical and morphological characteristics of Co3O4 nanoflowers, Fourier transform infrared spectroscopy (FTIR), X-ray diffractometry (XRD), field emission electron microscopy (FESEM), Energy dispersive spectroscopy (EDS), and was used. To determine the adsorbence mechanism in detail, eluent concentration, eluent type, solution pH, adsorbent amount, solution volume, and adsorption duration were studied. In these assessments, flame atomic absorption spectroscopy (FAAS) was used. For Cr6+, adsorption optimum parameters were determined as 3M HNO3, pH 6.5, 150mg, 30mL, 60min. For Cd2+, optimum parameters were determined as 3M HNO3, pH 6.0, 100mg, 10mL, 30min. Co3O4, nanoflowers are eco-friendly adsorbent materials for the adsorption of Cd6+ and Cd2+ heavy metal ions since the production method is affordable and practical.

Abstract

Bu çalışmada, hidrotermal yöntem ile kobalt(II/III) oksit (Co3O4) nançiçek yapılar laboratuvar şartlarında pratik bir şekilde sentezlendi. Krom ve kadmiyum gibi ağır metal iyonlarının uzaklaştırılması için bu nanoflowerların adsorban olarak uygulanması araştırıldı. Co3O4 nanoçiçeklerinin, morfolojik analizi ve kimyasal bileşimini karakterize etmek için X ışını kırınım analizi (XRD), alan emisyonlu taramalı elektron mikroskopisi (FESEM), enerji dağılım X-ışınları spektroskopisi (EDS) ve FTIR teknikleri kullanılarak gerçekleştirildi. Adsorpsiyon sisteminin optimum koşullarını belirlemek amacı ile elüent derişimi ve türü, çözeltinin pH’ı, adsorban miktarı, çözelti hacmi ve adsorpsiyon süresi gibi parametrelerin etkisi incelendi. Elde edilen çözeltide metal iyonlarının alevli atomik absorpsiyon spektrometrisi (FAAS) analiz sonuçları doğrultusunda optimumum parametreler belirlendi. Bu paremetre sonuçları sırasıyla Co3O4 nanoflowerı ile Cr6+ için 3 M HNO3, pH 6.5, 150 mg, 30 mL, 60 dk; Cd2+ için 3 M HNO3, pH 6, 100 mg, 10 mL, 30 dk olarak bulundu. Co3O4 nanoçiçekleri; adsorpsiyon kapasitelerinin yüksek olması, kolayca sentezlenebilir ve imalat maliyetlerinin nispeten düşük olmasından dolayı krom, kadmiyum ve diğer ağır metal iyonlarının sulu sistemlerden uzaklaştırılmasında verimli ve çevre dostu adsorbanlar olabileceklerini göstermektedirler.
