▎ 摘  要

NOVELTY - Preparing polyolefin solution metal ash removing agent comprises (i) adding graphene oxide to water to obtain a graphene oxide dispersion, (ii) adding a condensation activator into graphene oxide dispersion, stirring and reacting at 20-120°C for 10-120 minutes, (iii) adding triazine and condensing agent respectively, and stirring and reacting at 20-120°C for 10-120 minutes, and (iv) filtering, washing and drying to obtain the finished product. USE - The removing agent is useful in removing metal components in polyolefin solution (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for removing ash from metal of polyolefin solution, comprising passing polyolefin solution in adsorption column filled with polyolefin solution metal ash removing agent, and carrying out adsorption treatment to obtain a purified polyolefin solution.
