摘要

•Froth flotation was used to simultaneously remove Ni(II) and Cr(VI) from water.•Intelligent nano-hydrogels were prepared for serving as the collector.•Chitosan was used to improve adsorption of heavy metal ions on nano-hydrogels.•Temperature can significant affect the floatability of PNIPAM-CS nano-hydrogels.
