<div><p>Over the last decade, numerous removal methods using solid-supported magnetic nanocomposites have been employed in order to remove arsenic from aqueous solution. In this report, removal of arsenic from aqueous solution by an organo silica, namely, magnetic mobile crystalline material-41 (MCM-41) functionalized by chlorosulphonic acid (MMCM-41-SO<sub>3</sub>H), was investigated using atomic absorption spectroscopy. The synthesized magnetic mesoporous materials have satisfactory As (V) adsorption capacity. Linearity for arsenic was observed in the concentration range of 5–100 ppb. In addition, the coefficient of determination (<i>R</i><sup>2</sup>) was more than 0.999 and the limit of detection (LOD) was 0.061 ppb. Considering these results, MMCM-41-SO<sub>3</sub>H has a great potential for the removal of As (V) contaminants and potentially for the application in large-scale wastewater treatment plants.</p></div>
