abstract = {Bovine serum albumin (BSA) coated on citrate capped gold
nanoparticles (BSA-GNPs) was exposed to a simulated
wastewater effluent (SSE) in order to study the
mineralization and thereby mimic scaling at biofouled
membranes of reverse osmosis (RO) wastewater desalination
plants. RO is a leading technology of achieving freshwater
quality as it has the capability of removing both dissolved
inorganic salts and organic contaminants from tertiary
wastewater effluents. The aim was to better understand one
of the major problems facing this technology which is
fouling of the membranes, mainly biofouling and scaling by
calcium phosphate. The experiments were performed using the
small-angle neutron scattering (SANS) technique. The
nanoparticles, GNPs, stabilized by the citrate groups showed
30 Å large particles having a homogeneous distribution of
gold and citrate with a gold volume fraction of the order of
$1\%.$ On the average two BSA monomers are grafted at 2.4
GNPs. The exposed BSA-GNPs to SSE solution led to immediate
mineralization of stable composite particles of the order of
0.2 μm diameter and a mineral volume fraction between
$50\%$ and $80\%.$ The volume fraction of the mineral was of
the order of 10–5, which is roughly 3 times larger but an
order of magnitude smaller than the maximum possible
contents of respectively calcium phosphate and calcium
carbonate in the SSE solution. Considering the extreme low
solubility product of calcium phosphate, we suggest total
calcium phosphate and partially $(5–10\%)$ calcium
carbonate formation in the presence of BSA-GNPs.},
