Abstract

$NH_4^{+}$ removal by natural zeolites of two different types from Eskişehir and Çankırı was investigated in this study. In batch tests, maximum $NH4}^{+}$ removal was observed at the pH range between 5-6. At this range $NH_4^{+}$ removal efficiencies were determined as 81-87.5% for both zeolite types. $NH_4^{+}$adsorption isotherms were established for both zeolites and it was shown that the absorption data fit to the Langmuir izotherm better than the Freundlich. Langmuir izotherm coefficients were calculated as qm= 13.2 mg/g, K= 0.09 mg/L for the zeolite of Eskişehir; qm= 16.2 mg/g, K= 0.03 mg/L for the zeolite of Çankırı.

Özet

Bu çalışmada, Eskişehir ve Çankırı bölgelerinden elde edilen iki farklı doğal zeolit türü ile $NH_4^{+}$ giderimi incelenmiştir. Kesikli sistemde yürütülen çalışmalarda pH=5-6 arasında en yüksek $NH_4^{+}$ giderim verimliliği gözlenmiştir. Bu pH aralığında her iki zeolit için $NH_4^{+}$ giderim verimleri %81-87.5 olmuştur. Zeolitlerin $NH_4^{+}$ adsorpsiyon izotermleri çıkartılmıştır. Yapılan çalışmada adsorpsiyonun Langmuir izotermine daha iyi uyduğu saptanmıştır. Langmuir izoterm katsayıları Eskişehir bölgesindeki zeolit için qm=13.2 mg/g , K= 0.09mg/L, Çankırı bölgesindeki zeolit için ise qm=16.2 mg/g , K= 0.03 mg/L olarak hesaplanmıştır.
