Targeting organically-complexed iron species in seawater using selective solid-phase adsorbent resins. Iron limits primary productivity in 40% of the oceans. Its accurate determination is thus critical to understanding the functioning of marine ecosystems and their role in moderating Earth's climate. Recent findings indicate that serious discrepancies exist in iron concentrations obtained using different analytical methods. These discrepancies are believed to be due to the lability of organic ....Targeting organically-complexed iron species in seawater using selective solid-phase adsorbent resins. Iron limits primary productivity in 40% of the oceans. Its accurate determination is thus critical to understanding the functioning of marine ecosystems and their role in moderating Earth's climate. Recent findings indicate that serious discrepancies exist in iron concentrations obtained using different analytical methods. These discrepancies are believed to be due to the lability of organic and colloidal iron species to extraction by adsorbent preconcentration resins. This project will design and synthesise a range of functionalised resins for the selective extraction of iron species from seawater, advancing our knowledge of its bioavailability and leading to the generation of class-specific analytical methodologies.Read moreRead less
Automated Sensors for a ‘wetland in a box’. Globally, and particularly in Australia, water supply and water pollution is one of the most critical constraints to our health and growth. This project seeks to validate a new portable remediation system suitable for deployment at regional locations through the integration and development of advanced sensors. We aim to develop the world’s first completely integrated platform for monitoring both water chemistry and microbiology to provide near-real-tim ....Automated Sensors for a ‘wetland in a box’. Globally, and particularly in Australia, water supply and water pollution is one of the most critical constraints to our health and growth. This project seeks to validate a new portable remediation system suitable for deployment at regional locations through the integration and development of advanced sensors. We aim to develop the world’s first completely integrated platform for monitoring both water chemistry and microbiology to provide near-real-time information regarding the quality of the remediated water. We expect this to improve the availability of regional water resources by providing a low-cost remediation solution with integrated monitoring to provide assurances of meeting the Australian Guidelines for Water Recycling (2006).Read moreRead less
