Advanced Magnetic Adsorbents Prepared from Emulsion Template for Water Treatment

Adsorption technology regarded as an ideal method to remove water contaminants has been widely applied in practical applications, as the merit of the wide suitability and low cost. Among various adsorbents, magnetic recyclable adsorbents have gained more and more attention in recent years, which not only decrease the risk of secondary pollution but also realize the cyclic use of the adsorbent after being regenerated and even increase significantly the additional value for enriching the scattered metals and precious metals. Recently, more and more studies have concerned the morphological control, homogeneous size, and tuned porous structure of magnetic adsorbents except for the adsorption performance. Hence, the emulsion template technique is applied to construct the magnetic adsorbents based on the advantages of facilely controlling the size distribution, crystallinity, and porous structure of magnetic materials.
