| Abstract: | A bench scale experiment was conducted to study the extraction/back extraction process for recovering H acid (1 amino 8 naphathol 3, 6 disulfonic acid). The experimental result showed very high efficiencies of extraction and back extraction and unchanged quality of the recycled extractant. A high removal of organic matter (over 93%) from the mother liquor was obtained and condensation multiple of more than 10 times reached; thus the condensed liquid could be returned to the production of H acid. |
