A low cost hydrophobic kaolin hollow fiber membrane (h-KHFM) for arsenic removal from aqueous solution via direct contact membrane distillation
In this work, a low cost hydrophobic kaolin hollow fiber membranes (h-KHFM) was successfully prepared by phase inversion/sintering technique followed by a modification via grafting with fluoroalkylsilane (FAS) molecules. The influence of sintering temperature varied from 1200 to 1500 °C on the hydro...

In this work, a low cost hydrophobic kaolin hollow fiber membranes (h-KHFM) was successfully prepared by phase inversion/sintering technique followed by a modification via grafting with fluoroalkylsilane (FAS) molecules.

The results reveal that h-KHFM prepared at a sintering temperature of 1300° °C induced a high contact angle value of 145° an excellent LEPw value of 2 bar, and an average pore size of 0.32 µm.
