▎ 摘  要

NOVELTY - Method for dispersing and recovering of nanomaterials based on environmentally responsive polymers in aqueous phase involves (1) adding nanomaterials to an aqueous solution containing pollutants to obtain a mixed system, (2) dispersing environmentally responsive polymer uniformly in the mixed system to disperse the nanomaterials to obtain a uniform dispersion system and (3) dispersing the inorganic salt uniformly in the uniform dispersion system, performing environmental response treatment and shaking treatment, collecting after a floating layer appears on the surface of the aqueous solution and realizing the recovery of the nano-adsorbent material in the aqueous phase. USE - The method is useful for dispersing and recovering of nanomaterials based on environmentally responsive polymers in aqueous phase. ADVANTAGE - The method can use environmentally responsive polymers to improve the dispersibility of nanomaterials in aqueous solutions and to collect nanomaterials, has high collection efficiency and low cost and adopts simple and quick operation.
