| Abstract: | The amine salt extraction mehtod for recovery Naphthalene sulpho- nic acid dye intermediate from waste liquor has been investigated in this paper.It is found that the recovery of J acid urea was over 95%and the net benefit of recovery for 10 tons waste liquor daily is about 5.8 millions RMB yuan. The relationships among the amount of extractant,the content of dye intermediate in waste liquor and the extraction ratio have been decribed by using of Langmuir isotherm equation which may direct to develop the tech- nological design easily. |
