  • Sorbent for removing heavy metal ions from water
    Patent number: 7884043
    Abstract: The invention relates to sorption materials for removing of heavy metal ions from ground water and surface aquifer systems, and can be used by enterprises in chemical and metallurgical industry which utilize etching and galvanic technologies. The sorbent for removing of heavy metal ions from water is composed of ground zeolite and nanophase material, where the nanophase material consists of nanophase iron hydroxide and nanophase boehmite in the following ratio, mass %: Nanophase iron hydroxide 12-18 Nanophase boehmite ?5-13 Ground zeolite the rest. Technical result is the enhanced purification effectiveness of the sorbent due to a wider range of heavy metals it can absorb when purifying highly contaminated water.
