The author conducted a study on the adsorption behavior of yttrium and rare earth elements in sea water. These elements adsorbed themselves to glass or polyethylene and to suspended partides from the solution of pH5 to 8. Sample water, therefore, should be kept acidic (pH<3) after sampling.
As a result of fluorometric determination, sea water was found to contain about-0.15μg/lof yttrium, and above a half of the content was concerned with suspended matter.
Lanthanum and europium were determined by neutron activation, and the results were-0.04μg La/l and-0.002μg Eμ/l.
