Fabrication and characterization of electrospun PVDF-aliquat 336 fibre membrane for removal of cadmium from hydrochloric acid solutions
The use of polyvinylidene fluoride (PVDF) electrospun fibre membrane incorporating aliquat 336 for the removal of cadmium from hydrochloric acid solutions was investigated. Scanning electron microscopy (SEM) was used to determined fibre diameter and to observe the fibre morphology. Energy dispersive spectroscopy (EDS) analysis was carried out to follow the fate of the aliquat 336 in the fibre membrane formed via electrospinning process and to detect the presence of cadmium in fibre membrane after it has acted as an ion exchange media. The amount of cadmium removed by the fibre membranes was determined by flame atomic absorption spectroscopy. The maximum capacity of the PVDF-aliquat 336 electrospun fibre membranes was determined to be 0.46 mg/g.
