Özet:

 The current study aims to use Allium scorodoprasum L. biomass as an adsorbent for the bioremoval of Remazol black 5 RB5 dye from aqueous solutions. The binding capacity of Allium scorodoprasum L. biosorbent to RB5 was investigated by recording the changes in pH, concentration of RB5 dye, temperature and contact time in batch aqueous solutions. Dubinin-Radushkevich D-R, Freundlich, and Langmuir isotherm models were used to explain the experimental data. The maximum RB5 dye biosorption capacity of the biosorbent was found to be 19.8 mg g-1 at 25 oC. The average biosorption-free energy indicated that the biosorption event took place by chemical reaction and that it followed the PFO and IPD rate kinetics, respectively. Finally, thermodynamic adsorption studies indicated that the RB5 dye biosorption was both endothermic and spontaneous. The Allium scorodoprasum L. had a significant adsorption capacity for the anionic RB5 dye.

 Öz: Bu çalışma, Allium scorodoprasum L. biyokütlesini Remazol black 5 RB5 boyasının sulu çözeltilerden biyo-giderimi için bir adsorban olarak kullanmayı amaçlamaktadır. Allium scorodoprasum L. biyosorbentinin RB5e bağlanma kapasitesi, kesikli yürütülen adsorpsiyon çalışmlarında pH, RB5 boya konsantrasyonu, temas süresi ve sıcaklıktaki değişimler kaydedilerek araştırılmıştır Deneysel verileri açıklamak için Dubinin-Radushkevich D-R, Freundlich ve Langmuir izoterm modelleri kullanılmıştır. Biyosorbentin maksimum RB5 boya biyosorpsiyon kapasitesi 25 oCde 19,8 mg g-1 olarak bulunmuştur. Ortalama biyosorpsiyonsuz enerji, biyosorpsiyon olayının kimyasal reaksiyonla gerçekleştiğini ve sırasıyla PFO ve IPD hız kinetiğini takip ettiğini göstermiştir. Sonuç olarak, termodinamik adsorpsiyon çalışmaları RB5 boya biyosorpsiyonunun hem endotermik hem de spontane olduğunu göstermiştir. Allium scorodoprasum L. anyonik RB5 boyası için önemli bir adsorpsiyon kapasitesine sahiptir. .
