Abstract: ABSTRACT: This research aimed to propose an alternative cheap and abundantly available adsorbent (Ferula communis) for the removal of basic dyes from aqueous solutions. Chloroacetic acid modified Ferula communis (MFC) shows a great potential for the removal of basic red 9 dyes (BR9) from aqueous solution with the effects of solution capacity under pH, temperature, contact time, adsorbent dosage, and initial dye concentration condition on BR9 removal were examined. The adsorption equilibrium data were fitt to adsorption isotherm models and the pseudo-second order adsorption kinetics provides the best description of BR9 adsorption onto MFC. Thermodynamic evaluation of the adsorption parameters showed that the adsorption is endothermic and spontaneous. The experimental outcomes in the present research elucidated that MFC is suitable alternative to remove basic dyes. Keywords: Ferula communis, Basic red 9, Adsorption, Kinetics, Thermodynamic studies. ………………………………………………………………………………………………………………………… ÖZ: Bu araştırmanın amacı, sulu çözeltilerden bazik boyaların uzaklaştırılması için alternatif ucuz ve bol miktarda bulunabilen bir adsorban (Ferula communis) önermektir. Kloroasetik asit fonksiyonlandırılmıs Ferula communis (MFC), farklı pH, sıcaklık, temas süresi, adsorban bir dozaj ve ilk boya konsantrasyonu koşulları altında çözelti kapasitesinin etkileri ile sulu çözeltiden bazik kırmızı 9 (BR9) boyasının ortadan kaldırılması için önemli bir potansiyel göstermektedir. Adsorpsiyon denge verileri adsorpsiyon izotermi modellerine uygunlugu ve yalancı-ikinci derece adsorpsiyon kinetigi, MFC üzerine BR9 adsorpsiyonunu açıklamaktadır. Adsorpsiyon parametrelerin termodinamik olarak değerlendirilmesi, adsorpsiyonun endotermik ve kendiliğinden olduğunu göstermiştir. Mevcut araştırmadaki deneysel sonuçlar, MFC in bazik boyaların giderimi için uygun bir alternatif olduğunu göstermektedir.
