Transport of Chromium (Cr(VI)) Through Reverse Osmosis (RO), Nanofiltration (NF), and Ultrafiltration (UF) Membranes
铬(Cr(VI))通过反渗透(RO)、纳滤(NF)和超滤(UF)膜的传输
A bench-scale cross-flow flat-sheet filtration unit is being used to evaluate
short-term chromium (Cr (VI)) rejection by negatively charged membranes. Three
mechanisms, solution diffusion (dominant in RO), size exclusion (dominant in
NF), and electrostatic exclusion (dominant in UF), are being highlighted in this
study for chromium removal. In this study, RO, NF, and tight UF membranes
have been tested to evaluate the effects of pH and co- and counter ions on Cr
(VI) rejection.
