Adsorptive treatment with microbial biomass of 226 Ra-containing waste waters

The adsorption of 226Ra by dead microbial biomass (activated sludge and Penicillium chrysogenum) was investigated over the 226Ra concentration Fe2+ and CU2+ on the radium uptake capacity of the biomass was examined in detail. The results from the competitive adsorption studies were cor range was determined as the optimum for radium adsorption under all conditions. The IIA group of elements were shown to be the most effective radium ca
