▎ 摘 要
NOVELTY - Preparation of modified graphene oxide involves adding 0.5 g graphene oxide to 250 mL hexadecyltrimethylammonium bromide with concentration of 0.04 mol/L, reacting in water bath at 80 degrees C for 2-3 hours, separating, washing using distilled water, drying in vacuum at 50 degrees C, and grinding. USE - Preparation of modified graphene oxide used in removal of bisphenol A (claimed). ADVANTAGE - The method enables simple preparation of modified graphene oxide having excellent removal efficiency, with high recyclability using readily available materials. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for usage of modified graphene oxide in removal of bisphenol A.
