从历史上看，人们认为普里茨廷环境中存在的活性无机磷仅以正磷酸盐的形式存在。然而，这一假设与生物起源理论和所观察到的选定微生物的代谢行为相矛盾。本文讨论了离子色谱在阐明环境磷的氧化还原循环中的作用。这些方法采用抑制IC，再加上串联电导率和电喷雾质谱检测器，以识别和定量磷氧阴离子在天然水，合成宇宙化学和生物样品。这些技术已用于地热温泉中亚磷酸盐和正磷酸盐的检测。次磷酸盐、亚磷酸盐和正磷酸盐已在合成的钙铝石腐蚀样品和白蚁提取物上清液中检测到。还分析了合成的钙钛矿腐蚀样品中的两种多磷化合物，次磷酸盐和焦磷酸盐，结果显示这些样品的浓度分别不超过1.3和2.0 µM的检测3σ。这些方法很容易适应各种基质，并有助于阐明环境中的磷氧阴离子的氧化还原循环。与大多数研究相反，这些技术已被用于表明磷积极参与生物和地质世界的氧化还原过程。
Historically, it was assumed that reactive, inorganic phosphorus present in prictstine environments was solely in the form of orthophosphate. However, this assumption contradicts theories of biogenesis and the observed metabolic behavior of select microorganisms. This paper discusses the role of ion chromatography (IC) in elucidating the oxidation-reduction cycle of environmental phosphorus. These methods employ suppressed-IC, coupled with tandem conductivity and electrospray mass spectrometry detectors to identify and quantify phosphorus oxyanions in natural water, synthetic cosmochemical, and biological samples. These techniques have been used to detect phosphite and orthophosphate in geothermal hot springs. Hypophosphite, phosphite, and orthophosphate have been detected in synthetic schreibersite corrosion samples, and termite extract supernatant. Synthetic schreibersite corrosion samples were also analyzed for two poly-phosphorus compounds, hypophosphate and pyrophosphate, and results show these samples did not contain concentrations above the 1.3 and 2.0 µM respective 3σ of detection. These methods are readily adaptable to a variety of matrices, and contribute to the elucidation of the oxidation-reduction cycle of phosphorus oxyanions in the environment. In contrast to most studies, these techniques have been used to show that phosphorus actively participates in redox processes in both the biological and geological world.
