Influence of pore size and membrane surface properties on arsenic removal by nanofiltration membranes
Next Previous
Abstract
Four NF membranes were compared regarding arsenate rejection and their properties. Rejection of arsenate had no relationship with membrane pore size. A more negative surface charge was favorable for arsenate rejection at neutral pH. A severe membrane fouling could lead to a great reduction of arsenic rejection.
