The kinetics of radium biosorption

The intrinsic rate of radium adsorptive uptake by two types of waste inactive microbial biomass was examined. The effects of solution initial radium concentration, pH and ionic composition on the observed rate were also investigated. The results show that radicum uptake rates are reasonably rapid, with equilibrium attained after less than 2 min up to about 5 min, depending on the particular biosorption system and experimental conditions studied. The uptake of radium from industrial process wastewater is also rapid.
