Promotion of the Decomposition of the Odorous Compounds by Ozonation by Ethylenediaminctctraacetic Acid (EDTA) Metal Complexes

摘要

Kinetic studies on the decomposition of odorous compounds (geosmin and 2-methylisoborneol; 2-MIB) by ozonation in the presence of EDTA-metal complexes to accelerate the decomposition rate were carried out.2Na-EDTA accelerated the decomposition of 2-MIB in the natural water samples taken from Toyohira River, Sagami River, Edo River, Yodo River, and Kurose River. The K_(max) values of 2-MIB were 2.7, 8.7, 4.1, 8.3, and 5.6, respectively.
