Oil Water

The process in which the nanofiber membrane is used to remove heavy metal ions and separation of oil-water solution is analyzed. Herein, smooth structures are induced by rGO-g-PAO sheets, which could be attributed to the strong interaction between P(AN-MA) and rGO-g-PAO. It is rewarding to note that the P(AN-MA)/rGO-g-PAO nanofiber membrane would exhibit superhydrophilic traits in the air and ultra-low oil-adhesive traits underwater when the concentration of P(AN-MA) and PAO is 13 wt.% and 0.3 wt.%, respectively. The amidoxime (–C(NH2) NOH) groups on the membrane surface can efficiently adsorb copper (Cu(II)) (1.65 mmol/g) and chromium (Cr(VI)) (4.70 mmol/g) ions in the waste water. Meanwhile, the P(AN-MA)/rGO-g-PAO nanofiber membrane exhibits ultrahigh flux (~6150 LMH), satisfying rejection rate (~97%) and outstanding flux recovery ratio (~99%) in separating oil water emulsion.

Carbon materials are promising candidates for sensors to detect heavy metal ions. This paper reported an effective method of fabricating nanofiber membrane sensor for detection of heavy metal ions by electrospinning with the carbon nanoparticles and PANi (polyaniline) as additives. The results revealed that the PANi/C/PAN nanofiber membrane was the most economical approach to adsorbing and detecting metal ions with highly sensitive property. This paper sheds a light on an economic fabrication of nanofiber membrane sensor with well-defined characteristics in electrical sensors and adsorption applications.
