Abstract

A new method was used for experimental simulation of the sorption–desorption transformation of microelement composition of the adsorbed complex of solid substances of river runoff at the interaction with seawater. The experimental results suggest the conclusion that a change of freshwater to marine conditions is accompanied by desorption of some elements and sorption of others. The desorption increases the runoff into the World Ocean of dissolved forms of manganese, cobalt, nickel, cadmium, thallium, and barium by 102, 21.2, 4.0, 16.2, 4.8, and 21.1%, respectively, while the sorption leads to a decrease of the global river runoff of dissolved lead and cesium by 9.4 and 2.6%.

河海地球化学屏障中溶解性微量元素径流的吸附-解吸转化（基于实验实验室模拟的数据）

摘要

一种新方法被用于模拟河流径流固体物质在与海水相互作用下的吸附复合物的微量元素组成的吸附-解吸转化的实验。实验结果表明，淡水向海洋环境的变化伴随着某些元素的解吸和另一些元素的吸附。解吸使溶解态的锰，钴，镍，镉，th和钡的流入径流分别增加了102％，21.2％，4.0％，16.2％，4.8％和21.1％，而吸附导致减少。全球溶解的铅和铯的径流分别为9.4和2.6％。
