Synthesis of Fe3O4@BAMTM for removing inorganic and organic contaminants from an aqueous solution: Screening and optimization

Abstract

Nowadays Water is crucial for sustaining life, playing a vital role in public health and community well-being., one of the most intriguing challenges in water remediation is the elimination of heavy metals from industrial wastewater using materials that function as adsorbents. This study introduces a new nanocomposite called Fe3O4@BAMTM, which serves as an adsorbent and evaluates its effectiveness in removing heavy metals and Coomassie Brilliant Blue (CBB) from wastewater. The optimization of the adsorption process was carried out using the Box-Behnken Design (BBD) model in conjunction with the Response Surface Methodology (RSM). The optimal conditions for Coomassie Brilliant Blue (CBB) removal were determined to be a pH 2, a dosage 0.10 g/L, and a temperature 35℃, utilizing the Fe3O4@BAMTM NC, which exhibited superior adsorption capabilities, with an adsorption capacity of 555.56 mgCBB/gNC and rapid attainment of adsorption equilibrium (30 minutes). Furthermore, the Fe3O4@BAMTM demonstrated 67% and 65% removal of iron (III) and nitrate ions, respectively, from the wastewater.
