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.

铁限制了 40% 海洋的初级生产力。 因此，其准确测定对于了解海洋生态系统的功能及其在调节地球气候中的作用至关重要。 最近的研究结果表明，使用不同分析方法获得的铁浓度存在严重差异。 这些差异被认为是由于有机铁和胶体铁物质对吸附剂预浓缩树脂萃取的不稳定性造成的。 该项目将设计和合成一系列功能化树脂，用于从海水中选择性提取铁物质，提高我们对其生物利用度的了解，并产生特定类别的分析方法。
