Fluorine Removal in Aqueous Solutions Using ZnO Doped Chitosan

Abstract

In this study, it was aimed to prepare and analyze an environmentally friendly adsorbent because fluoride in water is an important health threat affecting the whole world. ZnO doped chitosan adsorbent was produced for fluorine adsorption. The characterization of the adsorbent was done by FT-IR, SEM-EDX analysis. The effects of pH, initial concentration, amount of adsorbent on adsorption were investigated. Langmuir and Temkin isotherm models were studied and Langmuir was found to be the most compatible isotherm. The maximum adsorption amount was calculated as 3.67 mg/g according to Langmuir isotherm.

ZnO Katkılı Kitosan Kullanılarak Sulu Çözeltilerde Flor Giderimi

Abstract

Bu çalışma, sulardaki Florürün bütün dünyayı etkileyen önemli bir sağlık tehdidi olması nedeniyle çevre dostu bir adsorbentin hazırlanarak incelenmesi amaçlanmıştır. ZnO katkılı kitosan adsorbenti Flor adsorpsiyonu için üretildi. Adsorbentin karakterizasyonu FT-IR, SEM-EDX analizler ile yapılmıştır. pH, başlangıç konsantrasyonu, adsorbent miktarının adsorpsiyon üzerine etkisi araştırıldı. Langmuir ve Temkin isotherm modelleri çalışıldı ve en uyumlu isothermin Langmuir olduğu bulunmuştur. Langmuir isothermine göre maksimum adsorpsiyon miktarının 3,67 mg/g olarak hesaplanmıştır.
