Abstract  

Adsorption of radium was studied on glass and polyethylene from aqueous solutions containing 8–40 pg·dm–3224Ra and on membrane filters, glass and polyethylene bottles from waste and river waters containing 2–170 pg·dm–3226Ra. The adsorption from aqueous solutions was determined as a function of pH and composition of the solutions and interpreted as due to ion exchange of Ra2+ ions for counter ions in the electric double layer on glass and polyethylene or due to chemisorption of RaSO4 (RaCO3) ion pairs on glass. Borosilicate glass adsorbed radium substantially more than polyethylene. The adsorption of dissolved forms of radium from the waste and river waters during storage and membrane filtration of the waters was negligible, but a significant loss of particulate forms of radium was sometimes observed during the storage. It has been recommended to separate dissolved and particulate forms of radium soon after the sampling and to prefer polyethylene to glass as container material for storage of dissolved forms of radium.
