Research Progress of Polyamide-amine Dendrimer Modified Separation Membrane in Water Treatment
Membrane separation technology is nowadays one of the most widely used technologies in water treatment,but the membrane used in the separation process is liable to contamination,thus affecting the separation performance and service life of the membrane.Polyamide-amine(PAMAM)dendrimers contain highly branched structure and a large number of terminal groups,which can be introduced into the separation membranes to endow the membrane with advantages,such as high water flux,high rejection rate and good anti-fouling property.At present,PAMAM modified separation membranes have been widely studied in the fields of drinking water purification,industrial wastewater treatment,seawater desalination and so on.This review mainly introduces the research progress of PAMAM modified ultrafiltration membrane,nanofiltration membrane,forward/reverse osmosis membrane and their applications in water treatment,and discusses the development direction of PAMAM modified separation membranes.
