The Study of the Degradation of the Phosphate Ester Catalyzed by the Nitrogen Unsaturated Heterocycle Cerium(III) Complex

Abstract:

Phosphate ester and its ramifications in the pesticide are virulent and some are known to be human carcinogens. The removal of phosphate ester in the leftover of the pesticide has been a major environmental concern. The Cerium(III) complex made up of a nitrogen unsaturated heterocycle ligand and Cerium ion(III) was used in the catalytic degradation of bis(4-nitrophenyl) phosphate ester (BNPP). This catalytic system showed higher catalytic activity and better reproducibility and stability than other similar Cerium(III) systems. The rate of the BNPP catalytic degradation was about 109 -fold faster than that of its spontaneous degradation at the same conditions. The Cerium(III) complex is an very effective catalyst in the degradation of the phosphate ester.
