NOVELTY - Preparing water purifying material involves adding graphite oxide in acetic acid solution with stirring to obtain graphene oxide solution, dissolving chitosan in water, adding acetic acid, generating colloidal liquid, adding titanium dioxide under constant reaction temperature, stirring for 2-4 hours, adding sodium hydroxide solution to form particles with diameter of 1 millimeter, taking out particle in cross-linking agent, reacting for 1.5 hours, washing by distilled water, freezing and drying to obtain titanium dioxide-chitosan-graphene oxide composite particle. USE - Method for preparing water purifying material (claimed). ADVANTAGE - The method enables to prepare water purifying material which has good absorption performance, stable property and increased anti-tensile property and is eco-friendly and convenient for recycling the water purifying material.
