Poly(ethylene glycol)/poly(ε-caprolactone) nanoparticles for removal of metal ions in micellar-enhanced ultrafiltration |
| 초록 |
Micellar-enhanced ultrafiltration (MEUF) has been shown to be a promising method for the removal of toxic heavy metal ions from industrial effluents. The advantage of this method are the low-energy requirements involved in the UF processes and its high removal efficiency owing to the effective trapping of solutes by the micelles. The amphiphilic nanoparticles (ANPs) composed of hydrophilic poly(ethylene glycol) and hydrophobic poly(epsilon-caprolactone) could be self-assembled to form micelles. The ANPs are available for the MEUF system due to low critical micelle concentration and high stability under trans-membrane pressure, in the results of reducing the secondary contamination caused by collapse of micelle. The purpose of this work is to evaluate the potential of ANPs for the removal of metal ions from aqueous phase in the MEUF, because the metal ions can be mostly trapped on the micelle surface. The removal efficiency of the metal ions was evaluated as the functions of trans-membrane pressure and concentrations of the ANPs. |
