The uptake kinetics of 3 2 P‐PO 4 added to water from a eutrophic lake are frequently biphasic; consequently the system cannot be described by a two‐compartment exchange model. Experiments in which uptake kinetics and the effectiveness with which hydrous zirconium oxide removes 32 P‐PO 4 from filtered lake water were measured concurrently showed that the biphasic kinetics cannot be explained by postulating an abiotic complexing of 32 P‐PO 4 with some other component of membrane filtered lake water.
