Modifiye Edilmiş Pomza Kullanılarak Sulu Ortamlardan Adsorpsiyon Prosesi ile Arsenat (V) Giderimi

Bu çalışmada, adsorpsiyon yöntemi ile sulu ortamdan As(V) giderimi için ham ve yüzeyi modifiye edilmiş pomzanın etkinliği incelenmiştir. Granüler destek malzemesi olarak Isparta pomzası kullanılmış ve demir oksit ile kaplanmıştır. Katı sorbentlerinin yapı karakterizasyonunun belirlenmesi için FTIR, XRD ve BET yüzey alanı analizi yapılmış ve yüzey morfolojisinin gözlenmesi için SEM görüntüleri kullanılmıştır. HIP ve DOKIPkatı sorbentleri kullanılarak sulu çözeltiden As(V) giderimini etkileyen çözelti pH’ı, başlangıç As(V) konsantrasyonu, temas süresi, adsorbent dozu ve sıcaklık parametreleri incelenmiş ve optimum giderim koşulları tespit edilmiştir. DOKIPiçin maksimum As(V) giderimi ve adsorpsiyon kapasitesi sırasıyla % 95,99±1,43 ve 1,92±0,03 mg/g olarak elde edilmiştir. DOKIP ile As(V) adsorpsiyonu için ΔH, ΔS ve ΔG termodinamik parametreleri hesaplanmış, adsorpsiyon prosesinin ekzotermik karakterli olduğu belirlenmiştir. Deneysel adsorpsiyon verilerinin Langmuir, Freundlich ve Dubinin-Radushkevich (D-R) izotermlerine uygunluğu incelenmiş ve adsorpsiyon verilerinin Langmuir modeline uyduğu belirlenmiştir. Yüksek adsorpsiyon kapasitelerine dayanarak, sulu çözeltilerden As (V)'in önderiştirilmesi ve gideriminde DOKIPsorbenti umut verici alternatif bir adsorban olarak önerilmiştir.

Removal of Arsenate (V) by Adsorptıon Process from Aqueous Media Using Modified Pumice

In this study, the efficiency of row and surface modified pumice was investigated for As (V) removal from aqueous media by adsorption method. Isparta pumice is used as granular support material and coated with iron oxides. FTIR, XRD and BET surface area analysis were performed for determination of solid sorbents structure characterization and SEM images were used for observation of surface morphology. The impacts of pH, initial As(V) concentration, contact time, adsorbent dose and temperature on As(V) removal were studied with using HIP and DOKIP as adsorbent and optimum removal conditions have been determined. The maximum As(V) removal and adsorption capacity of DOKIP-1 were 95.99±1.43 % and 1.92±0.03 mg/g, respectively. The ΔH, ΔG and ΔS thermodynamic parameters for As(V) adsorption of DOKIP are calculated and results showed that the adsorption process has exothermic character. The Langmuir, Freundlich and Dubinin–Radushkevich (D-R) isotherms were used to fit the equilibrium data. Langmuir model resulted in the best fit of the adsorption data. Based on high adsorption capacities, DOKIP sorbent has been proposed as a promising alternative adsorbent in the preconcentration and removal of As (V) from aqueous solutions.
