Nickel(II) grafted MCM-41: A novel sorbent for the removal of Naproxen from water

Preparation of amino-Fe(III) functionalized mesoporous silica for synergistic adsorption of tetracycline and copper

“…Amino-functionalized SBA15 has proved to be one of the most useful sorbents for removing heavy metals from water due to its excellent chelating ability (Aguado et al, 2009). Metal grafting SBA15 shows high adsorption capacity in the removal of pharmaceutical drugs for water treatment (Rivera-Jimenez and Hernandez-Maldonado, 2008;Rivera-Jimenez et al, 2010). In connection with the ability of Fe(III) to form stable complexes with antibiotics (Barbooti et al, 2014), we proposed an adsorbent with dual functionalization of amino groups and Fe(III) based on SBA15, for synergistic removal of antibiotics and heavy metals, whereas few studies have thoroughly discussed.…”

Adsorptive removal of selected pharmaceuticals by mesoporous silica SBA-15

“…Mesoporous materials have been investigated for adsorptive removal of various organics such as cyanuric acid and p-chlorophenol [16], phenols [17], and dyes [18][19][20] in aqueous solution. Recently, removal of naproxen on a MCM-41 incorporated with nickel(II) complexes has been reported [21]. However, only single component adsorption at mg L −1 -level concentration was investigated, while adsorption kinetic, isotherm, desorption results as well as effect of pH and chemical factors such as competing anions, humic acid on adsorption have been not considered.…”

Transition metal modified and partially calcined inorganic–organic pillared clays for the adsorption of salicylic acid, clofibric acid, carbamazepine, and caffeine from water

“…Recent initiatives to address the removal of PPCPs with minimal energy input or unwanted side products include adsorption processes [36][37][38][39][40][41][42][43]. Until recently, much of the effort made to advance water treatment adsorption processes has been focused on the removal of metals and other contaminants from water [44,45].…”

“…Hernandez-Maldonado and co-workers have already reported on the positive effect that inclusion of transition metals onto the surface of non-pillared IOCs, and even onto mesoporous silicas, has on the adsorption of some PPCPs [37,41,63]. Transition metals are known to undergo complexation with compounds containing aromatic groups based on an electron donation and back donation process.…”
