In this study, the removal of methyl orange (MO) from aqueous solutions by adsorption using modified orange peel (MPK) was investigated. The effects of contact time and initial MO concentration on the adsorption process on the efficiency were evaluated; the optimum conditions for MO removal were determined to be pH 2.11, initial MO concentration 350 mg/L and contact time 70 minutes. Changes in the surface morphology and chemical composition of MPK before and after adsorption were characterised by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and Fourier transform infrared spectroscopy (FTIR) analysis. The results showed that MO adsorption obeyed the Langmuir isotherm model and chemical adsorption and irreversibility effects played an important role. The maximum adsorption capacity for MO was calculated as 37.31, 39.06 and 41.49 mg/g at 25, 35 and 45 °C, respectively. Kinetic analyses showed that MO removal was consistent with the pseudo-second order (PSO) kinetic model. Overall, the high adsorption capacity and low cost of MPK make it an effective and applicable adsorbent for MO removal from aqueous media.

Modifiye Portakal Kabuğu ile Sulu Çözeltilerden Metil Oranjın Uzaklaştırılması

Öz

Bu çalışmada, modifiye edilmiş portakal kabuğu (MPK) kullanılarak sulu çözeltilerden metil oranjın (MO) adsorpsiyon yoluyla giderimi incelenmiştir. Adsorpsiyon sürecine etki eden temas süresi ve başlangıç MO konsantrasyonunun verimlilik üzerindeki etkileri değerlendirilmiş; optimum koşullar MO giderimi için en uygun koşulların pH 2.11, başlangıç MO konsantrasyonu 350 mg/L ve temas süresi 70 dakika olduğu belirlenmiştir. MPK’nın adsorpsiyon öncesi ve sonrası yüzey morfolojisi ile kimyasal bileşimindeki değişiklikler, taramalı elektron mikroskobu (SEM), enerji dağılım spektroskopisi (EDS) ve Fourier dönüşümlü kızılötesi spektroskopisi (FTIR) analizleri ile karakterize edilmiştir. Sonuçlar, MO adsorpsiyonunun Langmuir izoterm modeline uyduğunu ve kimyasal adsorpsiyon ile tersinmezlik etkilerinin önemli rol oynadığını göstermiştir. MO için maksimum adsorpsiyon kapasitesi 25, 35 ve 45 °C’de sırasıyla 37.31, 39.06 ve 41.49 mg/g olarak hesaplanmıştır. Kinetik analizler, MO gideriminin yalancı ikinci dereceden (PSO) kinetik modeli ile uyumlu olduğunu göstermiştir. Genel olarak, MPK'nın yüksek adsorpsiyon kapasitesi ve düşük maliyeti, onu sulu ortamlardan MO giderimi için etkili ve uygulanabilir bir adsorban yapmaktadır.
