abstract = {In the last decades, magnetic particles (MPs) as adsorbents have gained special attention due to their
high adsorption capacity and the possibility of recovering them by applying a magnetic separation
gradient. For the first time MPs have been tested as P adsorbents in a microcosm experiment in a context
of lake restoration. MPs were added to sediment cores from a hypertrophic lake, at Fe:PMobile molar ratio
of 285:1 and 560:1 under both, oxic and anoxic conditions. We have found that, under anoxic conditions
(anoxic), MPs are able to reduce P release rate from the sediment to the overlying water and to reduce
sedimentary PMobile concentration (a 22e25% reduction within 0e4 cm depth compared to controls).
Under oxic conditions, the addition of MPs do not affect P fluxes across the sediment and water interface
since the lake sediment is naturally rich in iron oxides. However a measured reduction in sedimentary
PMobile concentration (12e16% reduction in 0e10 cm depth) contributes to a potential reduction in longterm
P efflux.},
