چکیده
|
Humic acid (ha) is typical refractory components of natural organic matter (nom), which leads to the formation of disinfection by products, so it is necessary to separate from water flow# in this study, nanocomposite membranes was prepared for separating of humic acid from synthetic wastewater# ultrafiltration polysulfone membrane was fabricated by phase inversion technique then znse and znse/cdse nanoparticles were doposited on the membrane surface by photo polymerization method# results showed that the presence of znse and znse/cdse nanoparticles increased the contact angle by 53% and 45% that represents nanoparticles are hydrophobic# also znse and znse/cdse coated membranes have about 1 and 11% more porosity than raw membrane# moreover, the presence of znse and znse/cdse nanoparticles provide more pore number and lower torthuosity than raw membrane# aforementioned proprties results a flux enhancemnet from 55#75 for raw membrae to 65#44 and 58#25 l/m2#h for znse and znse/cdse coated membrane, respectively# on the other hand, decreased pore size of nanocomposite membranes provided increased rejection by 30% and 10% for znse and znse/cdse coated membrane compared to raw membrane#
