Abstract: It's found that 60Co and 137Cs concentrated by Plalymonas sp.can be washed out with 0.5% ethylene diamine sodium teracetate.The washed amount is decreased with increasing time of concentration and stabilized in the range of 42—48% after 16 hours.Loss experiment shows thatthe amount of 60Co and 137Cs in Plalymonas sp.is influenced by biotic dilution after cell multiplication.Potasium cyanide and iodcacetic acid can slightly inhibit the concentration of 60Coand 137Cs when added previously.However,when the inhibitors are added with 60Co and 137C sat the same time,the concentration of nuclides are premoted.It's considered that this promotion is not physiological action but physical and chemical adsorption.
