Abstract：

Nanofiltration　membrane　was　prepared　by　static　layer-by-layer　(LBL)　self-assembly　of　poly(ethyleneimine)　(PEI)　and　poly(sodium　4-styrenesulfonate)　(PSS)　on　the　modified　poly-arcylonitrile　ultra-filtration　membrane.　Study　on　self-assembly　of　polyelectrolyte　membranes　with　changing　surface　charges　and　wettability,　rejection　properties　of　nanofiltration　membrane　in　different　conditions　and　pH　with　respect　to　heavy　metal　ions,　namely　Ni2+　and　Cd2+were　investigated.　The　results　show　that　the　PEI/PSS　membrane　composed　of　4　bilayers　at　operating　pressure　0.4MPa,　rejection　of　PAN-PEI/PSS　nanofiltration　membrane　towards　these　2　kind　of　heavy　metal　ions　reached　no　less　than　90%.　©　(2014)　Trans　Tech　Publications,　Switzerland.
