▎ 摘  要

NOVELTY - Adsorbent material includes graphene oxide plates cross-linked by branched polymer nanoparticles. USE - Adsorbent material for removing contaminants from water. ADVANTAGE - The adsorbent material is cost-effective, eco-friendly, and shows fast performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method of removing contaminants from water, which involves filtering the water through the adsorbent material; and (2) a method of fabricating an adsorbent material, which involves preparing stock solutions of graphene oxide (GO) and high molecular weight branched polyetheleneimine (bPEI), both with pH adjusted to 7.0; combining the prepared stock solutions in a ratio of 10:1 GO:bPEI into a combined solution; mixing the combined solution; adjusting the pH of the combined solution to 5.5 after mixing the combined solution; adding at least one ketone to the combined solution after adjusting the pH to 5.5 to form a synthesized material in water; and separating the synthesized material from the water and rinsing the separated synthesized material with clean water.
