Microextraction of Gadolinium MRI contrast agent using core-shell Fe3O4@SiO2 nanoparticles: optimization of adsorption conditions and in-vitro study

Selective adsorption of gadolinium from real leachate using a natural bentonite clay

“…Adsorption capacity and selectivity are important factors in assessing the practicability of any adsorbent. Therefore, a comparison of Gd 3+ adsorption between Bentonite clay used in this work and other adsorbents reported in the literature was assessed [41][42][43][44][45][46][47][48] (see Table 3). The maximum adsorption capacity of our bentonite clay at pH 6 was found to be 121.5 mg g − 1 , which is the third highest among those of other materials presented in Table 3.…”

“…The maximum adsorption capacity of our bentonite clay at pH 6 was found to be 121.5 mg g − 1 , which is the third highest among those of other materials presented in Table 3. The first and second highest q max values were colloidal graphene oxide [46] and core-shell composite based on Fe 3 O 4 and SiO 2 [42], respectively. These materials possess much more complex synthesis routes at higher costs when compared to bentonite clay prepared in this work.…”

Green and sustainable palladium nanomagnetic catalyst stabilized by glucosamine‐functionalized Fe3O4@SiO2 nanoparticles for Suzuki and Heck reactions

“…[ 29,30 ] Additionally, the existence of hydroxyl functional groups on silica shell surface supply suitable sites for possible conjugation of varies function scaffolds. [ 31 ] Therefore, the obtained Fe 3 O 4 @SiO 2 nanostructures have ideally both features of magnetic nanoparticles and mesoporous silica layer. [ 32 ]…”
