Abstract: AOX was initially introduced as a sum parameter in 1976, the content of which in waste water and sludges has been limited in many countries due to its harmfulness to human beings and other bios when the quantity is excessive. Various adsorbable organic halogens can be formed in the processing and finishing of textiles which will lead to potential harm to humans if the amount of residue is too much in end-products.So it is necessary to build a common method of determining the residual quantity of AOX in textiles with which to control its content. In various test methods, IC has its advantage over micro coulometric titration,GC-MS, neutron activation and others as the method to test AOX in textiles.
