Efficient and Magnetic Adsorbent Prepared in a Dry Process with Enzymatic Hydrolysis Residues for Wastewater Treatment

Strategic Insights -

Researchers from Tianjin University of Science and Technology have developed a clean and facile dry process for preparing a novel magnetic absorbent using enzymatic hydrolysis residues (EHRs) and Fe3O4 nanoparticles. This approach eliminates the need for chemical reagents and reduces waste treatment, resulting in improved preparation efficiency. The adsorbent demonstrates high adsorption capacity for various pollutants, including Methylene blue, Congo red, and Cr (VI), with the highest adsorption capacities obtained at equilibrium stage being 562.17 mg/g, 587.94 mg/g, and 31.41 mg/g, respectively.
