A method of removing an organic pollutant from water that includes contacting contaminated water with a filtration membrane including sorbent particles of a spent fluid catalytic cracking catalyst (FCC) that includes a porous aluminosilicate material, and a carbonaceous material disposed on a surface of the porous aluminosilicate material, and a polymer support, to form a contaminated membrane, and collecting a purified water. The sorbent particles include 8.0-50.0 atom % carbon, based on a total number of atoms of sorbent particles, and the organic pollutant is at least one selected from the group including a dye, a phenol, a polycyclic aromatic hydrocarbon, an herbicide, a pesticide, and a persistent organic pollutant.

An adsorbent and a method of preparing the adsorbent are described. The adsorbent includes a 2-anthracene ammonium magnetic ionic liquid (MIL), and a [FeCl]or a [CoCl]ion. The adsorbents, 2-anthracene ammonium tetrachloroferrate (III) ([2AA] FeCl) and 2-anthracene ammonium trichlorocobaltate (II) ([2AA] CoCl), are prepared by protonation of 2-aminoanthracene, followed by complexation with FeCl/CoCl. The adsorbent of the present disclosure is effective in removing contaminants such as heavy metal ions from an aqueous system in a cost-efficient and selective manner.

A functionalized silica sorbent is described. The sorbent comprises mesoporous silica nanoparticles having a surface functionalized with a conjugated system comprising an azole and a phenyl. The surface may be functionalized by a Cu-catalyzed click reaction. The nanoparticles have an average particle size of 10-80 nm, and may be used to adsorb phenolic contaminants from aqueous solutions.

A method of preparing hydrodesulfurization catalysts having cobalt and molybdenum sulfide deposited on a support material containing mesoporous silica. The method utilizes a sulfur-containing silane that dually functions as a silica source and a sulfur precursor. The method involves an one-pot strategy for hydrothermal treatment and a single-step calcination and sulfidation procedure. The application of the hydrodesulfurization catalysts in treating a hydrocarbon feedstock containing sulfur compounds to produce a desulfurized hydrocarbon stream is also specified.
