Özet:

 In this study, the adsorption performance of nitric acid HNO₃-modified serpentine MS mineral in the removal of methyl oranıj MO from wastewater was evaluated. Various parameters affecting the adsorption process, especially contact time and initial MO concentration, were investigated and their effects on adsorption efficiency were investigated. As a result of the experiments, the optimum conditions for MO removal were determined as initial MO concentration of 300 mgL and contact time of 60 minutes. Changes in the surface morphology and chemical composition of MS before and after adsorption were analysed using scanning electron microscopy SEM, energy dispersive spectroscopy EDS and Fourier transform infrared spectroscopy FTIR techniques. The results obtained revealed that MO adsorption was in accordance with the Langmuir isotherm model and both chemical sorption and irreversibility effects played an important role in the adsorption process. The maximum adsorption capacity for MO was calculated as 36.90, 39.22 and 40.98 mgg at 25, 35 and 45 C, respectively. Furthermore, adsorption kinetics analyses revealed that the MO removal was in good agreement with the pseudo-second order PSO kinetic model. The results obtained show that MS is an effective and applicable adsorbent for the removal of MO dyestuff from aqueous media due to its high adsorption capacity, easy availability and cost effectiveness.

 Bu çalışmada, nitrik asit HNO₃ ile modifiye edilmiş serpentin MS mineralinin atıksulardan metil oranj MO giderimindeki adsorpsiyon performansı değerlendirilmiştir. Adsorpsiyon sürecine etki eden çeşitli parametreler, özellikle temas süresi ve başlangıç MO konsantrasyonu, incelenerek adsorpsiyon verimliliği üzerindeki etkileri araştırılmıştır. Yapılan deneyler sonucunda, MO giderimi için optimum koşullar başlangıç MO konsantrasyonu 300 mgL ve temas süresi 60 dakika olarak belirlenmiştir. MSnin adsorpsiyon öncesi ve sonrası yüzey morfolojisi ile kimyasal bileşimindeki değişiklikler, taramalı elektron mikroskobu SEM, enerji dağılım spektroskopisi EDS ve Fourier dönüşümlü kızılötesi spektroskopisi FTIR teknikleri kullanılarak analiz edilmiştir. Elde edilen bulgular, MO adsorpsiyonunun Langmuir izoterm modeli ile uyumlu olduğunu ve adsorpsiyon sürecinde hem kimyasal sorpsiyon hem de tersinmezlik etkilerinin önemli bir rol oynadığını ortaya koymuştur. MO için maksimum adsorpsiyon kapasitesi 25, 35 ve 45 C sıcaklıklarında sırasıyla 36.90, 39.22 ve 40.98 mgg olarak hesaplanmıştır. Ayrıca, adsorpsiyon kinetiği analizleri, MO gideriminin yalancı ikinci dereceden PSO kinetik modeli ile iyi bir uyum gösterdiğini ortaya koymuştur. Elde edilen sonuçlar, MSnin yüksek adsorpsiyon kapasitesi, kolay temin edilebilirliği ve maliyet etkinliği sayesinde sulu ortamlardan MO boyar maddesinin uzaklaştırılmasında etkili ve uygulanabilir bir adsorban olduğunu göstermektedir.
