Abstract Polycyclic aromatic hydrocarbons (PAHs) are one of the most recalcitrant pollutant originated from the burning of coal, petroleum, and other fossil fuels. The human exposure to PAHs may contribute to develop several carcinogenesis mechanisms. The aim of the present study was to develop a mixed matrix membrane (MMM) based on polyethersulfone (PES) and functionalized mesoporous material for the remediation of PAHs mixture by adsorption processes. MCM-41-based mesoparticles were obtained from biomass reuse of rice husk ash (RHA) and functionalized with p-aminobenzoic acid (PABA). The hydrothermal and casting methods were effective and sustainable in the preparation of PABA-MCM-41 and PES-based MMMs, respectively. PES-based MMMs presented an excellent distribution of the arrays incorporated and small-angle ordering. The absorption of PAHs was influenced by the incorporation of PABA-MCM-41 within the PES matrix.

<p>In the present paper, a synthesis of MCM-41 mesoporous material with the sodium silicate solution prepared from the rice husk ash as a silica source by the hydrothermal process was demonstrated. The influence of synthesized conditions such as CTAB concentration, SiO<sub>2</sub>/CTAB molar ratio, stirring time and hydrothermal time were investigated. The samples were characterized by XRD, FT–IR and N<sub>2</sub> adsorption–desorption measurement. The obtained results showed that the samples possessed highly ordered hexagonal mesostructure with uniform mesopore size distribution in a large range of CTAB concentration (1,98-4,81% mass) and the SiO<sub>2</sub>/CTAB molar ratio (4-15). The sample had a high surface area (1071 m<sup>2</sup>/g) and large pore diameter (33,5 Å) with the molar ratio of CTAB: SiO<sub>2</sub>: H<sub>2</sub>O = 1: 6: 1000.</p><p>Keywords: MCM-41, sodium silicate solution, rice husk ash</p>
