摘要
沉积物可溶性Ｆｅ￣（３＋）、Ｆｅ￣（２＋）含量变化，是反映氧化还原环境的重要指标之一，海洋沉积物Ｆｅ￣（３＋）／Ｆｅ￣（２＋）比值已被应用于海洋地质及油气化探上。可溶性亚铁很容易被氧化，为此我们进行了海洋沉积物可溶铁样保存条件（温度、时间）的试验研究。试验结果表明：在１０℃以下温度条件保存的海洋沉积物样品其可溶铁Ｆｅ￣（３＋）／Ｆｅ￣（２＋）比值在９０天内变化甚微。
The content of soluble Fe￣(3+) and Fe￣(2+) in sediment is one of the most important indi-cators reflecting the reduction-oxidation environment. The ratio of Fe￣(3+) /Fe￣(2+) in marinesediment has been applied to marine geology and geochemical exploration for oil andgas. In the case that soluble ferrous iron(Fe￣(2+))can be easily oxidated under normalcondition , the study is mainly focused on preservation condition for marine sedimentsample for soluble iron analysis (including temperature,time etc.)。 he result shows that the change of Fe￣(3+)/Fe￣(2+) ratio in the samples is very little af-ter they have been preserved for as long as 90 days in the place where the temperature isbelow 10℃.
