河水带下较多量的溶解硅酸盐(用“硅钼黄法”测出量称为“活性硅”),在河口处与海水混合过程中,溶解硅酸盐有没有一部分转移到非溶解相?是生物吸收转移为主还是无机化学转移为主?最后转移形成什么物质并归宿到何处?有多大部分重新参加硅的地球化学循环?如何循环?这些过程搞清楚,对研究硅在海洋中的地球化学、河口及近海海底沉积的形成与性质、港湾的淤积与变迁、生物的初级生产力以及河口各种水化学特征(进而涉及到河口各种污染物质的分布转移机理),都会有所帮助。它们一直是近十几年来国际上海洋化学工作者所注意的问题之一,然而直到现在仍然争论不休,没有取得一致见解。
In the river water, a large amount of dissolved silicates (measured as “active silicon” by the “molybdenum silicate yellow method”) are mixed with seawater, and part of the dissolved silicates are transferred to the undissolved phase What is the main component of the biosorption transfer or inorganic chemical transfer? What is the last transfer to form and where should it go? How much of it re-enter the geochemical cycle of silicon? How to cycle? These processes make it clear that the study of silicon in the ocean , The formation and nature of estuarine and offshore seabed sediments, siltation and change in harbor, primary biological productivity and various hydrochemical characteristics in estuaries, which in turn involve the distribution and transfer mechanisms of various pollutants in the estuaries . They have always been one of the problems that ocean chemistry workers in the world have been paying attention to in the past decade or so. However, there is still controversy so far and no consensus has been reached.
