abstract = {Alginate is an important part of the extracellular
polymeric substances excreted by microorganisms giving rise
to biofouling on reverse osmosis membranes in desalination
plants for water treatment. We present a small-angle neutron
scattering study on aggregation of alginate when exposed to
an aqueous salt solution simulating the reverse osmosis
concentrate of a wastewater reclamation plant. We explored
the behavior of alginate as dissolved molecule and as
grafted to the surface of gold nanoparticles thereby
simulating the condition of alginate attached at the surface
of a membrane. The behavior of dissolved and grafted
alginate was different when exposed to the simulation
solution. The dissolved alginate aggregates to a gel like
structure whereas the grafted alginate induces formation of
0.2 μm large particles. These particles form stable
composites within few seconds with volume fraction of about
half mineral and half gold nano-particles.},
