Aktif karbon, kil ve zeolit ile Malatya tekstil fabrikalarında kullanılan tekstil boyalarının adsorpsiyonu
Abstract
Bu
çalışmada, adsorban madde olarak, aktif karbon (Dew11Zn5), ham kil ve zeolit
kullanılmıştır. Dew11Zn5 aktif karbonu, atık kayısıdan ZnCl2 ile
kimyasal aktivasyonla hazırlanmıştır. Hekimhan-Malatya ham kil ve zeolit
örnekleri bu çalışmada diğer adsorban maddeler olarak kullanılmıştır.
Deneylerde kullanılan Aktif karbon (Dew11Zn5), ham kil ve zeolitin, BET yüzey
alanı, gözenek hacmi, ortalama gözenek çapı gibi gözenek özellikleri, N2
adsorpsiyon izotermini temel alan t-plot methodu ile karakterize edilmiştir.
Dew11Zn5, kil ve zeolitin BET yüzey alanı sırasıyla 1060, 7.61 ve 1.84 m2 /g
olarak tespit edilmiştir. Malatya tekstil işletmelerinde kullanılan 23 farklı
boya adsorplanan madde olarak seçilmiştir. Deneyler oda sıcaklığında 25o
C ve 1, 3, 12 ve 24 st’te gerçekleştirilmiştir. DB2RN boyasının zeolit üzerine
adsorpsiyon kinetiğinin incelenmesinde yalancı ikinci mertebe kinetik modeli
kullanılmıştır. Kinetik sonuçlar, DB2RN boyasının sulu çözeltiden zeolit
üzerine adsorpsiyonunun yalancı ikinci mertebe modele uyumlu olarak
gerçekleştiğini göstermektedir. Ayrıca, DB2RN boyasının zeolit üzerine
adsorpsiyon tipi, 500 mg/L boya konsantrasyonu için fiziksel adsorpsiyon, 1000
mg/L boya konsantrasyonu için kimyasal adsorpsiyon olduğu tespit edilmiştir.
Adsorpsiyon mekanizmasının açıkça değerlendirilmesi için intrapartikül difüzyon
modeli kullanılmıştır. İntrapartikül difüzyon modeli sonuçları, yalnızca
partikül içine difüzyonun hız kontrol basamağı olmadığı aynı zamanda sınır
tabaka difüzyonunun da adsorpsiyon hızını kontrol edebildiğini göstermektedir.
