Endüstriyel atık
sular içerisinde bulunan ağır metal iyonlarının giderimi için adsorpsiyon
etkili bir yöntemdir. Kullanılan adsorbentlerin verimliliğinin artırılması
tanecik boyutunun mikron altına indirgenmesiyle mümkündür. Dolayısıyla, bu
çalışmada zeolit nano-tanecikler klasik hidrotermal yönteme göre sentezlenerek
kurşun, nikel, bakır, gümüş ve metilen mavisi için adsorpsiyon kapasiteleri
kesikli proseslerde 25˚C sabit sıcaklıkta, farklı adsorbent ve kirletici
konsantrasyonlarında belirlenmiştir. X-ışını kırınımı (XRD), elektron taramalı
mikroskop (SEM) ve enerji dağılımlı X-ışını (EDX) analiz sonuçları, üretilen
zeolit nanotaneciklerin, yaklaşık 170 nm boyutunda çok küçük ve düzgün tanecik
yapısına sahip, Si/Al oranı 1.24 olan saf NaX-FAU olduğunu göstermiştir.
25˚C’de yapılan kesikli adsorpsiyon çalışmaları, NaX nanotaneciklerin kirletici
bileşenlere karşı yüksek afiniteye sahip olduğunu göstermiştir. Başlangıç metal
iyonu ve boyar madde konsantrasyonlarının artırıldığı durumlarda, NaX sorpsiyon
kapasitesi artmıştır ve kurşun, nikel, bakır, gümüş ve metilen mavisi için
sırasıyla 0.99, 1.33, 2.11, 1.89 ve 0.15 mmol/g maksimum değerlere ulaşmıştır. Sips
izoterm model denklemi bütün kirleticiler için elde edilen deneysel denge
değerlerini başarılı bir şekilde tanımlamıştır. NaX’in gerçek bir atıksu
içerisindeki ağır metal adsorpsiyon deneyleri, çözelti içerisinde kalsiyum ve
potasyum iyon konsantrasyonlarının yüksek olmasına rağmen, düşük konsantrasyondaki
kurşun ve nikeli yüksek oranda tutabileceğini göstermiştir.
