چکیده    In this study, novel polycarbonatetitanium oxide nanotubes (pctnt) ultrafiltration mixed matrix membranes (mmms) were fabricated for decontamination of cd^2+ and cu^2+ metal ions from aqueous solution. the weight percent of tnts in the polycarbonate membrane matrix was changed from 0 to 15. the synthesized neat pc membrane and pctnts mmms were characterized with respect to structural morphology and hydrophilicity using scanning electron microscopy (sem) and water contact angle, respectively. the effects of tnts loadings on the pure water flux, mean pore size, porosity and water contact angle of fabricated membranes and cd^2+ and cu^2+ heavy metal ion rejection were also studied. by increasing the loading of tnts nanoparticles in the membrane matrix, the membrane mean pore size tended to increase, while the porosity decreased. also, the increase in tnts loading resulted in an increase in membrane water flux which was mainly attributable to the enhancement in mean pore size and partly caused by the decreased contact angle value (more hydrophilic). of all the membranes studied, it was found by uf experiments that pctnt mmm was the most efficient material in heavy metal ions removal due to the superior adsorption capacity of tnts material. the generic results revealed that tnts material can be favorite candidates for mmms preparation in order to be conveniently used in the cd^2+ and cu^2+ heavy metal ions decontamination from polluted water resources.
