Description
Molecules (organic and inorganic) which can bind radioelements are usually termed complexants. Often the resulting complexes are water soluble, in which case the radioelement concentration in the porewater is increased, i.e. the solubility of the radioelement concerned is increased and its sorption properties are decreased. Examples of complexants are: ISA (cellulose degradation product) in cement porewater; cement additives; carbonate in the groundwater; humic substances in the groundwater; and cyanide and sulphides from the waste. Complexants increase solubility limits and reduce sorption of the radioelement concerned.
