Chemical Degradation of 2,3,7,8 - TCDD by means of Polyethylenglycols in the Presence of Weak Bases and an Oxidant
A CHEMICAL METHOD FOR DESTROYING THE 2,3,7,8-TCDD IS REPORTED; IT PROVIDES GRADUAL AND PROGRESSIVE SUBSTITUTION OF CHLORINE ATOMS BY HYDROGEN ATOMS. THE DEHALOGENATION IS PROMOTED BY A MIXTURE MADE UP OF POLYETHYLENGLYCOLS (HIGH MOLECULAR WEIGHT) OF A WEAK BASE (K2CO3) AND OF AN INORGANIC PEROXIDE (NA202) WHICH BEGINS THE RADICAL PROCESS. THE ORGANIC CHLORINE IS TRANSFORMED INTO INORGANIC CHLORIDE. THE REACTION MIXTURE ADMINISTERED TO MALE GUINEA-PIGS DID NOT LEAD TO ANY DIRECT OR HYSTOLOGICAL EFFECT.
