摘要: Abstract Mg–Zn ferrites with porous cavity structure were produced by sol-gel auto-combustion method utilizing a new mixture of dl -alanine and urea as an organic fuel-reductant. The influence non-magnetic Zn ions content on the structural, morphological adsorption characteristics NPs has been investigated. It was found that effects porosity ferrospinels. X-ray diffraction analysis confirmed formation cubic spinel phase crystallite size calculated SSP method, W-H modified Scherrer formula. SEM observations revealed mesh-like microstructure presence 1–2 μm macropores agglomerated nanoparticles. EDS spectra desired chemical composition powders. Mossbauer spectroscopy valence state cations their distribution over sublattices. compounds studied Congo Red dye removal. appropriateness Langmuir, Freundlich, Dubinin-Radushkevich models investigated parameters all determined. observed data fitted well Langmuir model, indicating occurred homogeneous surface active centers possessed similar energy values. isotherm model utilized to calculate free adsorption, i.e. setting in range 7.81–22.4 kJ/mol affects mechanism onto ferrite surfaces removal efficiency is enhanced rise content.
