Abstract: Porous material supported water treatment agent is an effective and environmental friendly composite material. It can be widely used to remove metal ions from wastewater. It has advantages of high specific surface area, high efficiency and easy recovery. This paper describes an overview of recent domestic and foreign new methods of porous material supported water treatment agent. Research progresses on preparation of supercritical technology, micro-emulsion technology, microwave technology and sol-gel technology, as well as the preparation method features were introduced. Meanwhile, the application of supported water treatment agent for non-ferrous metal ions, rare earth ions and noble metal ions was reviewed. The direction of development of waste water treatment agent to remove metal ions was specially proposed. More work needs to be done in improving reactivity of waste water treatment agent, adsorption and photocatalytic synergies. Materials containing functional groups as the support should be selected with the metal ions action. Magnetic load water treatment agent should be prepared to facilitate post-recycling. Environmental friendly and recyclable water treatment agent should be developed to improve life and avoid secondary pollution.
