Description: 

This research project will explore the potential for removing nanoplastics from drinking water using point-of-use household filtration systems. Nanoplastics, due to their small size and widespread presence in water sources, present a significant emerging concern for public health and environmental sustainability. While many traditional water filtration systems have been shown to effectively remove larger particles, little is known about their efficiency in filtering out nanoplastics, which can pass through standard filters and potentially enter drinking water supplies. This study will evaluate the effectiveness of various household water filtration systems, such as activated carbon filters, reverse osmosis units, and ceramic filters, in removing nanoplastics from contaminated water. By spiking drinking water samples with synthetic nanoplastic particles, the project will assess the efficiency of different filtration methods at various flow rates, pressure conditions, and filter types. The filtration systems will be tested under real-world conditions, mimicking common household usage.

The project will employ a range of advanced analytical techniques, including scanning electron microscopy (SEM), transmission electron microscopy (TEM), nanoparticle tracking analysis (NTA), and AF4 and Pyrolysis GCMS to detect and quantify nanoplastics before and after filtration. The study will also explore factors such as filter longevity, maintenance, and potential for particle re-release over time. This research aims to provide crucial data on the viability of household filtration systems in mitigating nanoplastic contamination, offering insights into practical solutions for consumers seeking to protect their drinking water from plastic pollution. The findings could inform recommendations for more effective filtration technologies and contribute to policy discussions on improving water quality standards to safeguard public health

Additional Information: This project is open to applications from students with a passion for science and plenty of curiosity. A background in chemistry / analytical chemistry / environmental chemistry would be highly beneficial.
