Enhanced antifouling performance of halloysite nanotubes (HNTs) blended poly(vinyl chloride) (PVC/HNTs) ultrafiltration membranes: For water treatment

Publication date: 25 July 2018Source: Journal of Industrial and Engineering Chemistry, Volume 63Author(s): Gourav Mishra, Mausumi MukhopadhyayAbstractNovel halloysite nanotubes (HNTs) embedded poly(vinyl chloride) ultrafiltration (UF) membrane (PVC/HNTs) were prepared and examined by FTIR, FEG-SEM-EDX, TEM, and SPM. In PVC/HNTs 1 and PVC/HNTs 2 membrane, HNTs were finely distributed and membrane surface became smooth. Pure water flux of the prepared membrane increased from 127.33 L m−2 h−1 for PVC/HNTs 0 membrane to 212.22 L m−2 h−1 for PVC/HNTs 2 membrane. Flux recovery ratio increased from 77.23% (PVC/HNTs0) to 92.10% (PVC/HNTs2) for BSA and 71.42% (PVC/HNTs0) to 92.16% (PVC/HNTs2) for sewage water. BSA rejection ratio was 93% for PVC/HNTs 2 membrane and the addition of HNTs as fillers increased the maximum tensile strength of the membranes.Graphical abstract
