Cetyltrimethylammonium bromide as a pore-forming agent was eliminated from the structure through a combination of two methods (calcination and modified extraction via supercritical CO₂). This inventive strategy leads to form magnetic mesoporous silica microspheres that enhance the capacity of adsorption of Pb²⁺, (ca. 989 mg g⁻¹). In addition, the recycling of this adsorbent from aqueous medium using high gradient magnetic separation (HGMS) was also explored and for obtaining the efficiency of separation some tests were accomplished using different matrix geometries. The separation efficiency of adsorbent via fine-matrix was more successful than a coarse matrix. Utilizing a combined arrangement of a fine and a coarse matrix, the performance of the separation was increased considerably comparing the single-stage separation chamber. About 93% of the magnetic adsorbent could be separated when the flow rate and magnitude of the magnetic field were fixed at 7.2 mL s⁻¹ and 0.33 m T, respectively. Generally, this work was developed high efficient adsorbent for water treatment and well planned separation of adsorbent from treated water by HGMS that can be used in a large-scale.]]> Wed 07 Feb 2024 16:37:11 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:35789 Tue 30 May 2023 10:59:21 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:513 Thu 25 Jul 2013 09:10:26 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:511 Thu 25 Jul 2013 09:10:25 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:363 Sat 24 Mar 2018 07:42:37 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:39744 Fri 17 Jun 2022 18:27:07 AEST ]]>
