Size fractionation of phosphorus (dissolved, colloidal and particulate) in two tributaries to Lake Lugano

Abstract

An in-situ fractionation mainly consisting of continuous flow centrifugation and cross-flow-ultrafiltration was used to separate a particulate (particle diameter >1 μm), a colloidal (particle diameter <1 μm and molecular weight >10 kD) and a dissolved fraction (molecular weight <10 kD) of total phosphorus in river water. A similar fractionation pattern is… (More)
