The~- object~ hsve been realiz-d accordi~g to the present i~vention by ue ns of for ing the above rentio~ed ~atrix from ~.o3t~6s a uranium compatible mutant suitable for receiving uranium dissolved in sea water. In this connection it has proved particularly advantageous to employ a matrix which is formed of single-celled green algae, but it is to be under-stood that also multi-celled algae are usable in this connection.
For the sake of completeness, it may be added that it is known that mutants of one-celled green algae are uranium compatible. It has also been speculated that such algae might be suitable for obtaining uranium from sea water, but heretofore no teaching has been disclosed how to go about technically to realize this speculation.
This invention seeks to provide a method of preparing a matrix comprising in combination mutants for single-cell green algae to be cultivated compatible with uranium and suitable for extracting uranium dissolved in sea water, which includes the steps of: introducing the algae into a sterilized nutrient solution adjusted to an acidity of pH 6, and formed of 3.8 grams sea salt, 0.03 grams of NH4N03 as well as 5 ml earth extracts in 100 ml water, introducing in steps into the thus obtained solution uranium in the form of uranylnitrate until the quantity of uranium has been enriched to 250 mg/l, subjecting the algae to x-ray radiation at a dose of approximately 50 kR, pouring the algae onto agar plates formed by employing a solution of 3.8 grams sea salt and 0.03 grams of NH4N03 and 5 ml earth extracts in 100 ml water, inoculating the thus forming colonies individually and further cultivating the same in a nutrient solution formed by the solution of 3.8 grams sea salt and 0.03 grams NH4N03 and 5 ml earth extracts in 100 ml water.
A preferred method of practicing the present invention consists in that the matrix is arranged in a filter cage with at least two screen-shaped walls which permit sea water to pass through but which are non-perme-able for the above mentioned mutants. The mesh size of the screen walls em-ployed for the filter cages must be less than the size of the cells of the mutants forming the matrix. Therefore, the cell size of the algae forming the matrix should be around from 50 to 100 ~.
ia38168 For obtaining uranium compatible algae, green algae are in con-formity with the present invention introduced into a solution with a high uranium concentration which solution contains sea water or the essential components of sea water whereupon the thus obtained solution with the algae therein is subjected to radiation by x-rays. The remaining algae are sown on a uranium containing nutritive substratum or nutrient medium, and the surviving cultures are taken off therefrom and are kept in pure sea water for forming a mass culture.
In order to obtain uranium from sea water, a flow of sea water is passed through the matrix formed according to the invention.
According to another modification according to the present invention for the obtainment of uranium from sea water, the matrix arranged in a filter cage is provided in an area of the sea which is subjected to the tides so that the flows or currents caused by the low tide and high tide are passed through filter cages surrounding the matrix. The total cross section of the matrix should in such an instance be approximately 100 square meters in order that with the flow velocity in the sea water as it is caused on an average by the tides generally in the vicinity of the shore will generate a through-flow rate through the cage of 106t sea water per day.
