摘要：

New cellulose fibrous sorbents, containing a diethylenetriamine tetraacetate groups, are proposed for the preconcentration of heavy metals. Quantitative extraction of heavy metals from river and sea water is achieved in a wide pH range (3-8) at a high solution flow rate (up to 100-150 volumes of sorbent per minute). Quantitative desorption of metals is achieved with a very small volume of the acid.
