Biosorption of uranium and thorium by Marine micro algae

Abstract

Different concentration of uranium and thorium uptake by algal biomass was studied. <i style="">Chlorella salina</i> and <i style="">Isochrysis galbana</i> was used to uptake the uranium and thorium in the present study. Different concentration of live cells of algae was also used to uptake the uranium and thorium. Increasing concentration of uranium and thorium showed decrease in absorption by <i style="">Chlorella salina</i> and <i style="">Isochrysis galbana</i>. Increase in biomass concentration has the ability to uptake more amounts of uranium and thorium. <i style="">Chlorella salina</i> absorbed more amount of metal than the <i style="">Isochrysis galbana</i>. Amount of uranium was uptake more than the thorium by <i style="">Chlorella salina</i> and <i style="">Isochrysis galbana</i>. <i style="">Chlorella salina</i> absorbed more amount of thorium.
