Abstract

In recent years, chemicals and drugs used in industry and agriculture have started to be harmful to all living things in the environments in which they are discharged. With the regulations prepared by environmental protection agencies and municipalities, hazardous chemicals are classified and minimum concentrations in wastewater are determined. Purification and purification processes have become mandatory for wastewater outside these limit values. In our study, the removal of phenol (P) and 4-chlorophenol (4-CP) with modified alkyl ammonium nanobentonite (MANB) from the aqueous solution was investigated. Balance time, concentration, pH effect, adsorban dosage effect and desorption were investigated in P and 4-CP adsorption. Adsorbed amount; 4.69 mg/g for P and 6.18 mg/g for 4-CP. Balance time 45 min. and the adsorbent desorption was performed in 30% (v/v) ethyl alcohol medium. Adsorption experiments were carried out at different temperature ranges of 25, 35 and 45C. Chemical structure, thermal and morphological characterization of samples were performed at the beginning and after adsorption. The suitability of the initial concentrations of the studied substances to the MANB microspheres was investigated for Langmuir and Freundlich adsorption isotherm models.

Modifiye Nanobentonitle Sulu Ortamdan Fenol ve 4-Klorofenolün Giderilmesi

Abstract

Son yıllarda endüstri ve tarımda kullanılan kimyasal ve ilaçlar deşarj edildikleri ortamlarda tüm canlılar için zararlı olmaya başlamıştır. Çevre koruma ajansları ve belediye gibi kurumların bu konudaki hazırladıkları yönetmeliklerle zararlı kimyasallar sınıflandırılmış ve atık sulardaki bulunabilecekleri minimum derişimler belirlenmiştir. Bu sınır değerler dışında kalan atık sular için saflaştırma ve arıtma prosesleri zorunlu hale gelmiştir. Çalışmamızda fenol (P) ve 4-klorofenolün (4-CP) modifiye alkil amonyum nanobentonit (MANB) ile kesikli sistemde, sulu çözeltiden giderimi araştırılmıştır. P ve 4-CP adsorplanmasında denge zamanı, konsantrasyon, pH etkisi, adsorbent dozaj etkisi ve desorpsiyonu incelenmiştir. Adsorplanan miktarı; P için 4,69 mg/g, 4-CP için 6,18 mg/g olarak elde edilmiştir. Denge zamanı 45 dak. olup adsorbentin desorpsiyonu % 30 (v/v)’ luk etil alkol ortamında yapılmıştır. Adsorpsiyon deneyleriı 25, 35 ve 45C değişik sıcaklık aralıklarında yapılmıştır. Örneklerin kimyasal yapı, termal ve morfolojik karakterizasyonu başlangıçta ve adsorpsiyondan sonra yapılmıştır. Çalışılan maddelerin başlangıç derişiminin MANB mikrokürelerin Langmuir ve Freundlich adsorpsiyon izoterm modellerine uygunluğu incelenmiştir. Deneysel bulguların Freundlich izoterm adsorpsiyon modeline uygun olduğu saptanmıştır.
