Highly
used
antibiotics,
such
as
amoxicillin
(AMX),
are
frequently
detected
in
the
aquatic
environment
due
to
contaminated
effluent
disposal,
alerting
for
possible
induction
of
antimicrobial
resistance.
In
this
study,
photodegradation
AMX
under
simulated
solar
radiation
and
environmental
influencing
factors
affecting
process
(pH,
salinity,
presence
humic
substances
or
reactive
oxygen
species
scavengers)
were
evaluated

its

Photodegradation
was
shown
be
faster
at

(t1/2

On

Through
use

scavengers
(propan-2-ol

respectively),
it
concluded
that
main
pathway

(PBS)
is
indirect
via
•OH.
Freshwater
