Author(s): Duraikkannu Shanthana Lakshmi*, Latha C. S and Mohan D
The performance of membranes for a specific application can be determined with the help of structural properties
such as Molecular Weight Cutoff (MWCO), morphology and pore statistics. Heavy metal ions from aqueous streams
can be separated with the help of ultrafiltration membranes. MWCOs and pore statistics of Polyurethane (PU) and
Carboxylated Polysulfone (Cpsf) blend ultrafiltration in the presence and absence of the various composition of the
additive poly (ethylene glycol) 600 were studied with the help of dextran of different molecular weights ranging from
19 kDa to 150 kDa. The derived pore size, porosity and number of pores have a remarkable relationship with the
MWCO, morphology and the flux performance of the membranes. Certain toxic divalent heavy metal ions such as
copper, cadmium, nickel and zinc were subjected to rejection by the blend membranes by c.. View more»
