Bu
çalışmada, Zostera marina L. atık
biyoması ile sucul ortamdan model bir sentetik azo boyanın (basic red 46)
biyosorpsiyonu ilk kez araştırılmıştır. Deneysel veriler, boya gideriminin
önemli bir şekilde biyosorbent miktarı, boya konsantrasyonu ve temas süresine
bağlı olduğunu göstermiştir. Biyosorpsiyon kinetik verileri, yalancı birinci
mertebe, yalancı ikinci mertebe, Elovich ve parçacık içi difüzyon modelleri
kullanılarak analiz edilmiştir. Freundlich, Langmuir ve Dubinin-Radushkevich
modelleri, deneysel izoterm verilerini modellemek için kullanılmıştır.
Modelleme çalışmaları sonuçları, Elovich ve Freundlich modellerinin,
biyosorpsiyon kinetik ve izoterm verilerine en iyi uyumu sağladığını
göstermiştir. Termodinamik çalışmalar, biyosorpsiyon prosesinin doğasını ortaya
koymak için yapılmıştır ve elde edilen sonuçlar, biyosorpsiyon sisteminin,
spontan ve fiziksel bir doğaya sahip olduğuna işaret etmiştir. Elde edilen tüm
bulgular, bu doğal biyolojik atığın, su ortamından böyle kirletici ajanların
uzaklaştırılması için uygun maliyetli bir biyosorbent materyali olarak etkili
bir şekilde kullanılabileceğini göstermiştir.
