NOVELTY - Recycling of waste plastic into best material for remediation of waste water system comprises synthesizing nanomaterial foam of polyethylene-graphene oxide-N doped titanium dioxide for toxic pollutant removal from water, where the method comprises nanofoam capable of removing the organic pollutant from waste water. USE - The method is useful for recycling of waste plastic into best material for remediation of waste water system. ADVANTAGE - The method: provides treated water from easy-to-access resources; improves in quality of treated water from various sources; and has the characteristics of good separation effect, high resource recovery rate, and no secondary pollution.
