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

In the MD simulations, the temperature and silica content loading varied from 25–45 °C and 0–20 wt%, respectively. In the DOE study, the range for the temperature and silica content loading variation was kept the same as considered in the MD simulations. The experimental pressure in the DOE was 0–10 bar. The experimental and simulation results were in good agreement and showed that the three most significant factors on the membrane performance from highest to lowest were silica particle loading, temperature and pressure, respectively.]]> Fri 25 Nov 2022 10:37:22 AEDT ]]>
