Abstract

Özet: Hümik asitler
gibi, doğal polimerlerin yapısal alt birimlerinden birini temsil eden gallik
asitler, sucul sistemlerde doğal organik madde bozunmasının bir ürünü olarak
kabul edilmektedir. Bu çalışmada, hümik maddelere yapısal olarak benzerlik
gösteren küçük moleküler ağırlıklı gallik asit, model madde olarak
değerlendirilmiştir. Gallik asidin fotokatalitik oksidasyonu, i) başlangıç
madde konsantrasyonu, ii) fotokatalizör konsantrasyonu ve iii) fotokatalizör
tipi gibi temel operasyon parametrelerinin etkisi araştırılarak incelenmiştir.
Fotokatalizör olarak TiO₂ Degussa P-25, Hombikat UV-100, PC-10,
PC-50 ve PC-105 kullanılmıştır. Gallik asidin zamana karşı fotokatalitik olarak
giderimi, UV-vis ve floresans spektroskopik parametreler ve toplam organik
karbon ölçümleri ile takip edilmiş ve birinci mertebeden kinetik model
kullanılarak açıklanmıştır. Gallik asidin kinetik verilerinin, ana molekül olan
hümik asidin fotokatalitik bozunma çalışmalarıyla ilişkilendirilebilmesi için
karşılaştırmalı bir yaklaşım izlenmiştir. Gallik asidin farklı fotokatalizörler
üzerindeki ön adsorpsiyon sonuçları, gallik asidin fotokatalitik giderim hızı
ile doğru orantılı olarak ilişkilendirmiştir. Gallik asit giderim hız
sabitlerinin UV₂₆₅ cinsinden karşılaştırılması; P-25> PC-10>
UV-100> PC-105> PC-50 şekilinde sıralanırken, toplam organik karbon
giderimi için hız sabitleri değişimi; PC-105> UV 100> PC-10> P-25>
PC-50 olarak bulunmuştur. Test edilen çeşitli fotokatalizörler arasında PC-105'
in, gallik asit giderimi için oldukça aktif olduğu bulunmuştur. PC-10 ve PC-50'
nin küçük yüzey alanları göz önünde bulundurulduğunda, bu fotokatalizörlerin
varlığında nispeten düşük giderim hızları elde edilmiştir.
