Description
A new method for the enrichment of trace multielement in nature water has been presented. The adsorption of four kinds of chelating agent(NaDDTC, Oxin, PAN and BPHA) on active carbon and the elution power of some solvents for these chelating agents have been studied. The static and dynamic adsorption of more than 20 metal elements on these chelating agents-active carbon at different pH values was discussed at the same time. Using a column with 80 mm x 10 mm I.D., different species of trace element in nature water on the spot can be enriched, and K, Na, Ca and Mg in water can be retained. The recovery of Be is in the range of 90%-108%. The elements can be determined by various detection methods
