Abstract

In this article, the authors present some results of study on environmental geochemistry and the capability of using weathered basalts from the Cồn Cỏ and Lý Sơn Islands, serving the sustainable development of sea and islands in Việt Nam. These islands are just Cenozoic volcanoes. The capability of cation exchange of weathered basalts from these two islands is much higher than those in other areas, making us to infer about their capability of heavy metal adsorption that makes them to have the capability of being used as raw materials in the treatment of heavy metal contamination of waste-water, serving the answer of a urgent requirement at the present time.
