Abstract:

This paper describes the basic selectivity principles of polydentate ligands. There were considered choices of structure modification of crown ethers to enhancetheir complexing properties. There was compared a complexstability and the selectivity of the various metal cations of oxygen-containingcrown ethers with the nitrogen-containing crown ethers.

Keywords:

crown ether; chelate; structure modification; sorbent; complex stability; cations
