adsorbents, Magnesium ferrite (MgFe<sub><span style=\"font-family:Verdana;\">2</span></sub><span style=\"font-family:Verdana;\">O</span><sub><span style=\"font-family:Verdana;\">4</span></sub><span style=\"font-family:Verdana;\">) nanoparticles
were synthesized using three different types of fuel such as Urea, Oxalic acid,
and Citric acid via sol-gel auto-combustion method. The prepared products were
characterized by means of powder X-Ray Diffraction (XRD), Fourier Transform
Infrared spectroscopy (FT-IR) and Field Emission Scanning Electron Microscope
(FE-SEM). The influence of the fuel used on the morphology and the crystallite
size of MgFe</span><sub><span style=\"font-family:Verdana;\">2</span></sub><span style=\"font-family:Verdana;\">O</span><sub><span style=\"font-family:Verdana;\">4</span></sub><span style=\"font-family:Verdana;\"> Nano products w</span><span style=\"font-family:Verdana;\"><span style=\"font-family:Verdana;\"><span style=\"font-family:Verdana;\">ere</span></span></span><span><span><span style=\"font-family:;\" \"=\"\"><span style=\"font-family:Verdana;\"> studied. The results showed that Citric acid fuel produced pure MgFe</span><sub><span style=\"font-family:Verdana;\">2</span></sub><span style=\"font-family:Verdana;\">O</span><sub><span style=\"font-family:Verdana;\">4</span></sub><span style=\"font-family:Verdana;\"> with the smallest crystallite size average cluster = 13.53 nm. The synthesized
sample was used for the removal of  <sup>99</sup>TcO<sub>4</sub><sup style=\"margin-left:-6px;\">-</sup> anions from
low level liquid waste under studied conditions. The different parameters
affecting on the adsorption process using the batch method were studied. The
results revealed that MgFe</span><sub><span style=\"font-family:Verdana;\">2</span></sub><span style=\"font-family:Verdana;\">O</span><sub><span style=\"font-family:Verdana;\">4</span></sub><span style=\"font-family:Verdana;\"> nanostructure has high
removal ability of <sup>99</sup>TcO<sub>4</sub><sup style=\"margin-left:-6px;\">-</sup> from aqueous
solutions (98.84%). The adsorption data are in good agreement with Freundlich
and Pseudo second order isotherm models. The adsorption process was a
chemisorption reaction additionally, the results of the thermodynamic
parameters indicated that the adsorption of <sup>99</sup>TcO<sub>4</sub><sup style=\"margin-left:-6px;\">-</sup> on
nanostructures was an exothermic and spontaneous process.</span></span></span></span>
