Abstract:
The wastew ater from the production of py romellitic acid is treated by cooperative ex tractio n with an efficiency o ver 99. 5%. The efficiency remains the same even w hen the regenerated ex trating reagent is used after recycling for more than 20 t imes. The effect of some factors on the extr acting efficiency is also disscussed in the paper.
