Method & Evidence

AimTo investigate the efficacy of modified brick materials as adsorbents for removing soluble iron from contaminated water sources.

MethodExperimental investigation and material characterization

ProcedureBricks were modified through acid activation and thermal treatments to enhance their adsorptive properties. The chemical composition, crystalline structure, and morphological characteristics of the raw and modified bricks were analyzed using various techniques (FTIR, ESEM/EDS, RX, NMR, TGA/MS, TGA/ATD, BET surface area analysis, ICP-AES). The adsorption kinetics of Fe(II) onto iron oxyhydroxide-coated bricks were studied, and thermodynamic parameters were evaluated. Finally, column studies were conducted using prepared composite materials to assess their performance in removing iron from aqueous solutions, with the Thomas model applied to analyze column parameters.
