Removal Of Pharmaceutically Active Compounds In Environmental Waters Using Polymer Inclusion Membranes.
PhD thesis, Perpustakaan Hamzah Sendut.
Abstract
The presence of residues of pharmaceutically active compounds in aquatic
environments is a daunting issue of great concern. The occurrence, fate and potential
toxicity of these contaminants in different environmental media have triggered the
interest of the science community. They have been found in varying concentrations
from ng/L to mg/L in different environmental matrices. As a result of their high
solubility and low volatility, they are often found in the aquatic environment and the
wastewater treatment plants (WWTPs) are their major reservoir. However,
conventional WWTPs are incapable of removing these contaminants completely
during treatments; hence, there is a need to explore other advanced wastewater
treatments to compensate for the lapses of conventional WWTPs. In this study, an
investigation on the removal of recalcitrant contaminants such as ciprofloxacin (CIP),
sulfamethoxazole (SMZ), and diclofenac (DCF) from wastewater using polymer
inclusion membranes (PIMs) fabricated from different base polymers (polyvinyl
chloride (PVC) and cellulose triacetate (CTA), different carriers (bis-2-(ethylhexyl)
phosphate (B2EHP) and tricapryl-methylammonium chloride (Aliquat 336)), and
different plasticizers (dioctyl phthalate (DOP) and 2-nitro phenyl ether (NPOE)).
