A comparative study on the synthesis of magnesium ferrite for the adsorption of metal ions: Insights into the essential role of crystallite size and surface hydroxyl groups

Modification of the crystallographic parameters in a biomaterial employing a series of gamma radiation doses

“…Due to microstrain, crystallite distortion occurs which results in a change of properties of materials, more precisely their applicability. A steady variation in microstrain has appeared from the estimated data which were generated by utilizing eqn (8) and are presented here in Table 2. With the addition of gamma radiation dose to the HAp samples, the value of microstrain was linearly decreased.…”

“…Most of the researchers have been concentrating on only the crystallite size of materials due to the larger surface area. [8][9][10][11] Other crystallographic properties are very significant in materials' applicability. Various reaction parameters are the controlling factors of nano-material synthesis such as reagent concentration, 12 temperature and ripening time, 13 pH, 14 etc.…”

Adsorptive removal of pollutants from water using magnesium ferrite nanoadsorbent: a promising future material for water purification

“…Appropriate temperature and time are required for crystal growth. Besides that, if the temperature cannot reach up to a certain value required for metal-oxide formation, the metals exit as hydroxide phase, which is unstable in water and can be easily solubilized in water (Candeia et al 2006;Nonkumwong et al 2015;Ivanets et al 2021b).…”

“…Large specific surface area, tunable pore size, high pore density, low cost, catalytic, photocatalytic and strong superparamagnetic characteristics made magnesium ferrite nanoscale adsorbents superior to others in water treatment (Tang et al 2013a;Jung et al 2017). Magnesium ferrite can adsorb both anions and cations from water at neutral pH (Ivanets et al 2021b). The adsorption rates for pollutants are very fast, and small adsorbent doses are required for efficient adsorption compared with other adsorbents (Tang et al 2013a).…”

“…Morphological properties affecting adsorption capacity depend highly on synthesis process, types of precursor materials and iron-magnesium ratio, etc. (Ivanets et al 2021b).…”
