This paper reviewed the toxicity,source and control methods of heavy metal ions,the progress of heavy metal chelator and composite materials were also introduced. The progress of heavy metal chelating composite materials from macromolecule resin,silicon particles,biomass materials, nanoparticles and mesoporous materials as matrics were analyzed and discussed. The future research directions were proposed as the following: the selection of matrix materials should focus on the sources,price and properties of materials,biomass materials,mesoporous materials and nano-porous materials should be selected with priority; new efficient chelating functional groups should be explored and developed;and the preparation and use of composite material must be pollution free and compatible with environment.
