Asitle Aktiflenmiş Bentonitin Termal ve Gaz Adsorpsiyonu Özelliklerinin İncelenmesi

Bu çalışmada, Ünye yöresinden alınan doğal bentonit (B) ve 90 oC'de 2 saat süresince asitle işleme tabii tutulan formlarının (1 M (BH-1) ve 2 M (BH-2)) SO2 adsorpsiyonu 20 oC sıcaklıkta ve 106 kPa basınçta incelenmiştir. Doğal ve asitle aktiflenmiş bentonit numuneleri, XRD, TG-DTA ve azot (N2) adsorpsiyon yöntemleri kullanılarak karakterize edilmiştir. Asit konsantrasyonu arttıkça bentonit numunelerinin hem yüzey alanlarında hem de SO2 gaz adsorpsiyonunda artış görülmüştür. Doğal ve asitle aktiflenmiş bentonit numunelerinin SO2 adsorplama kapasitelerinin B
