Polyamidoamine

composed of centre core and highly symmetrical dense outer layer

is dendritically shaped molecule with quantities of functional groups

the amount of which increases geometrically with the generation growth. The unique structures determine particular performances. Consequently

it has been widely applied in environmental contamination treatment. The paper refers to the structures

the synthesis of PAMAM

as well as reviews of their up-to-date research on the application of polluted water treatment. It is proposed that they have a better application prospects in water treatment aspect

and the future research direction on this very aspect is put forward.
