Abstract

Particle size has an important role among
parameters that can be effect the adsorption process such as temperature, pH
and contact time.  In this study, effect
of the particle size on the adsorption of methylene blue from aqueous solution
was investigated using apricot kernel shells with different particle sizes. In
the batch adsorption experiments made by using materials with an average
particle size of 1500 μm, For an average particle size of 1500 μm, obtained
removal efficiency and adsorption capacity of methylene blue in the batch
adsorption experiment were determined as 38.47% and 7.69 mg/g, respectively. By
reducing the average particle size to 106.5 μm, removal efficiency and
adsorption capacity increased to 92.64% and 18.53 mg/g, respectively. Reduction
of the particle size causes a significant increase in the contact surface
between the methylene blue molecules and the adsorbent material. The increase
of the contact surface ensures that a higher adsorption capacity together with
a shorter time period to reach equilibrium. As a result, it has been concluded that the particle size and contact surface have a
considerable effect on the adsorption process.

KAYISI ÇEKİRDEĞİ KABUKLARI İLE SULU ÇÖZELTİDEN METİLEN MAVİSİ ADSORPSİYONUNA PARTİKÜL BOYUTUNUN ETKİSİ

Abstract

Partikül
boyutu; sıcaklık, pH, temas süresi gibi adsorpsiyon sürecini etkileyebilen
parametreler arasında önemli bir yere sahiptir. Bu çalışmada farklı partikül
boyutlarına sahip kayısı çekirdeği kabukları kullanılarak sulu çözeltiden
metilen mavisi adsorpsiyonunda partikül boyutunun etkisi araştırılmıştır. 1500 µm
ortalama partikül boyutu için kesikli adsorpsiyon deneyinde elde edilen metilen
mavisi giderim verimi ve adsorpsiyon kapasitesi sırasıyla %38.47 ve 7.69 mg/g
olarak belirlenmiştir. Ortalama partikül boyutunun 106.5 µm değerine
düşürülmesiyle giderim verimi ve adsorpsiyon kapasitesi sırasıyla % 92.64 ve
18.53 mg/g değerine yükselmiştir. Partikül boyutunun azalması metilen mavisi
molekülleri ile adsorban madde arasındaki temas yüzeyinin önemli ölçüde
artmasına neden olmuştur. Temas yüzeyinin artması dengeye ulaşmak için daha
kısa bir zaman periyodu ile birlikte daha yüksek adsorpsiyon kapasitesi elde
edilmesini sağlar. Sonuç olarak partikül boyutu ve temas yüzeyinin adsorpsiyon
sürecinde oldukça önemli bir etkiye sahip olduğu sonucuna varılmıştır.
