چکیده انگلیسی
In this study photodegradation of enrofloxacin (ENRO) in aquatic media was performed at two different pH values, 4 and 8. Four and three photodegradation products (PDPs) with different molecular weight were identified at pH 4 and 8, respectively. All of them, together with the enrofloxacin as the parent compound were removed almost completely (>99%) by reverse osmosis (RO) and tight nanofiltration (NF) membranes, while by loose NF membranes >92%, except for the smallest PDP with HL membrane (37%) at pH 8. The minimum amount of the compounds in the permeate is the proof that most of the selected RO/NF membranes make an effective barrier for them. The size exclusion was the main rejection mechanism, while the physico-chemical interactions and electrostatic repulsion/attraction probably had influence on the overall rejection by loose NF membranes for the smaller photodegradation products of ENRO.
