摘要

Polyazacyloalkanes having 3, 4 or 5 nitrogen atoms, tri, tetra or pentaazamacrocyclic transition metal complexes and methods for the manufacture of said polyazacycloalkanes. The object of the invention is to provide polyazacyloalkanes capable of trapping metal cations and, in particular U, Pu, Am, Ce, Eu, Al, Gd, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ag, Cd, Sn, Au, Mg or Pb or complexes capable of trapping oxygen especially in a gas mixture. The invention is suitable, in particular, for treating liquid effluents discharged by nuclear power plants.
