The authors have previously developed the separation principles of filtering water samples rich in colloids into size fractions by the method of cascade filtration and by studying the migration of trace elements with them. Data acquired by studying the migration of a great number (forty to sixty) elements and organic matter (OM) of riverine runoff show that the method is highly promising for the separation of size fractions in search for stable geochemical associations of trace elements variably adsorbed on suspensions. Filtration with the application of seven to ten filter nominals, with the systematically decreasing pore diameter, was proven to be an efficient method for studying trace-element complexation with dispersed organic matter (DOM) in water bodies. However, the application of membrane filters made of organic materials of various nature (Nylon 6, lavsan, modified nitrocellulose, etc.) places certain constraints, which are caused not so much by the adsorption activity of the membranes but mostly by the rapid clogging of pores in the membranes with the gel-like amorphous precipitate. The paper is devoted to analysis of the newly suggested method of continuous gel-filtration.

大陆径流胶体水文地球化学实验基础

作者之前已经开发了通过级联过滤的方法将富含胶体的水样过滤成尺寸级分的分离原理，并通过研究微量元素随它们的迁移。通过研究河流径流中大量（四十到六十）元素和有机质 (OM) 的迁移获得的数据表明，该方法非常有希望用于分离粒度级分，以寻找不同吸附在表面上的微量元素的稳定地球化学组合。暂停。使用 7 到 10 个标称过滤器进行过滤，系统地减小孔径，已被证明是研究水体中微量元素与分散有机物 (DOM) 络合的有效方法。然而，由各种性质的有机材料（尼龙 6、lavsan、改性硝化纤维等）制成的膜过滤器的应用存在一定的限制，这不是由膜的吸附活性引起的，而主要是由膜孔的快速堵塞引起的。具有凝胶状无定形沉淀物的膜。该论文致力于分析新提出的连续凝胶过滤方法。
