河口海区为江河所携带泥沙、悬浮物等主要沉积场所,在沉积过程中有悬浮物的吸附和聚沉作用。为了研究该地区环境和沉积过程中载带元素的情况。开展了对沿海地区沉积物进行调查研究。在海洋、湖泊的沉积物中所含铁的化合物是少量的,而且这些物质主要是从溶解在水中的物质慢慢沉降而形成的,所以结晶也较差,因而用一些常规方法很难鉴别。而穆斯堡尔效应能对丰度低、颗粒小(>100)的含铁物质提供氧化态和化学组成等信息。铁在自然界中是以Fe~(+3)离子和Fe~(+2)离子存在于地球表面,在沉积物中也不例外。它们的存在形式取
The estuarine and coastal areas carry sediment and suspended sediment and other major sedimentary places for the rivers. During the sedimentation process, they have the effect of adsorption and sedimentation of suspended solids. In order to study the environment and sediment carrying elements in the area. Conducted a survey of sediments in the coastal areas. The compounds of iron contained in the sediments of oceans and lakes are small, and these substances are mainly formed by the slow sedimentation of substances dissolved in water, so that the crystals are also poor and thus difficult to discriminate by some conventional methods. The Mössbauer effect provides information on the oxidation state and chemical composition of iron-containing materials with low abundance and small particles (> 100). Iron in nature is based on Fe ~ (+3) ions and Fe ~ (+2) ions in the Earth’s surface, in the sediment is no exception. They take the form of existence
