Tek basamakta termal yöntem ile elde edilen manyetik (Fe3O4) kömür nanokompozitleri üzerine metilen mavisinin (MB) adsorpsiyonu incelenmiştir. ARCFe3O4 x kompozitleri Fe(NO3)3. 9H2O’ün dört farklı (x = 0.5, 1, 2 ve 3) oran olacak şekilde sentezlenmiştir. Nanokompozitler, taramalı elektron mikroskobu (SEM), X-ışını kırınımı (XRD) ve N2 adsorpsiyonu ile karakterize edilmişlerdir. ARCFe3O4 x kompozitlerinin denge ve hız deneyleri kesikli sistemde gerçekleştirilmiştir. Deneysel denge verileri Langmuir ve Freundlich izoterm modelleri ile karşılaştırılmıştır. Ayrıca nanokompozitlerin/MB pseudo-birinci ve ikinci derece kinetik modellere uygunluğu analiz edilmiştir. Tüm ARCFe3O4 x/MB sistemlerinin pseudo-birinci derece kinetik modeli ile uyumlu olduğu bulunmuştur.

Magnetic (Fe3O4) coal nanocomposites obtained using thermal method in one-step and the removal of methylene blue (MB) was investigated. ARCFe3O4 x composites were synthesized in four different ratios (x = 0.5, 1, 2 and 3) of Fe(NO3)3. 9H2O. The nanocomposites were characterized by scanning electron microscope (SEM), X-ray diffraction (XRD) and N2 adsorption. Equilibrium and rate experiments of ARCFe3O4 x composites were carried out in batch system. Experimental equilibrium analysis was compared with Langmuir and Freundlich isotherm models. In addition, nanocomposite/MB system has been determined for pseudo-first and second degree kinetic models. It was found that all ARCFe3O4 x/MB systems are compatible with the pseudo-first order kinetic model.
