Abstract

1472626 Algal mutants; extracting uranium from sea-water KERNFORSCHUNGSANLAGE JULICH GmbH 6 Sept 1974 [8 Sept 1973 30 Aug 1974] 39055/74 Headings C6F and C7D Algae are used to extract uranium from seawater by absorption and the absorbed uranium is recovered from the algal cells by conventional procedures e.g. by extraction by means of tributyl phospate. The algal cells of size 50-100Á may be held in a filter cage of 100m<SP>2</SP> cross-section exposed to a tidal flow of sea-water amounting to 10<SP>6</SP> tons per day. A preferred procedure involves the use of mutants of naturally occurring unicellular green algae obtained in a conventional fashion with x-ray irradiation. The selected mutants are capable of absorbing uranium from sea-water to a greater extent than the naturally occurring cells from which they derive and are compatible with relatively high concentrations of uranium of at least 2 ppm, even up to 500 ppm.
