Abstract:

Heavy metals are of a serious concern in the environment.Unlike other pollutants, their accumulation into the water system pose a great environmental impact due to their persistency into water bodies, non-biodegradability and their highly toxicity. In this study, membrane technological processes which make use of polyamide thin film composite (PA TFC) membranes for reverse osmosis desalination processes modified with zinc oxide nanoparticles (ZnO) and acrylic acid (AA) smart polymers are employed for the adsorption of heavy metals from acid mine water. The polyamide thin film composite membranes modified with ZnO nanoparticles and acrylic acid smart polymers were successfully synthesized using interfacial polymerization method and applied for the adsorption of lead from lead nitrate synthetic solution. The unmodified and modified membranes were evaluated for flux and rejection performance at different pH levels using a dead-end cell system. The hydrophilicity study of the membranes were also studied at different pH levels using a contact angle analysis. The morphological studies of the membranes were also conducted using XRD, AFM and SEM. The membranes were also evaluated for their chemical analysis using ATR-FTIR. Atomic absorption spectroscopy (AAS) have been used in order to evaluate the concentration of lead after the adsorption with polyamide thin film composite (PA TFC) membranes modified with zinc oxide nanoparticles (ZnO) and acrylic acid (AA) smart polymers (PA TFC/ ZnO/AA) during the rejection studies. The outcomes show pH sensitivity and improved membrane performance (flux and rejection) due to the incorporation of ZnO and AA.
