海水中元素的赋存形式
species of elements in sea water

  haishuizhong yuansu defueun xingshi海水中元素的赋存形式(speeie。of elelllellt、in seawater)某种元素存在于海水中的物理和化学形态。至今,一般的海水化学调查往往只局限于测定元素在海水中总的含量,这是远远不够的,因为要想开发和利用海水化学资源,就必须了解这些元素在海水中的存在形态,以便采取适当的方法加以提取。 占海水中可溶盐类99%以上的8种主要阳、阴离子即Na+、K+、M才十、Caz+、Cl一、Hc衡、c诱一、和洲一,除了以自由离子形式存在外,还有相当程度是以离子对形式存在的(CI一属例外,它不与任何主要阳离子形成离子对)。表中列出了这些海水主要成分的形态分布。 某些海水主要成分的形态分布离子浓度(md/l)自由离子(%)硫酸盐(%)碳酸氢盐(%)碳酸盐(%)CaZ+0 .010 4 91 8 1 0.2M扩十0 .054 0 87 11 1 0.3Na+ 0 .475 2 99 1.2 0.田1一K+0.0100 991一一 自由离子(%)钙盐(%)镁盐(%)钠盐(%)钾盐(%)S暖一0 .028 4 54 3 21.5 210乃H(:呀0.朋2 38 69 4 198一c咪一住。刃269 9 7 6717一 对于海水中大多数微量和痕量元素,除表已列出它们在海水中存在的主要化学形态外,它们还可以自由离子、水合离子、无机络合物、有机络合物及鳌合物,以及与高分子量有机物结合等形式存在于可溶态。另外,按其在海水中形成的粒径大小,有的自身形成胶体颗粒,或以一定形式吸附在胶体颗粒上(胶态),有的形成沉淀物,矿物颗粒,有机颗粒以及存在于活的生物体或死的生物残骸中(悬浮态)。了解元素在海水中的赋存形式,对于掌握它们在海水中的化学性质、迁移变化规律,以解决如何在海水中利用和提取这些元素是十分必要的。 (余国辉)
