摘要：

Complexation of some heavy metal cations in aqueous solution by diaza crown ethers and cryptands has been studied using pa-metric titrations. In most cases, macrobicyclic cryptands form more stable complexes than diaza crown ethers. The size of the cavity also influences the stability of the complexes formed.
