| Abstract: | Calcium magnesium acetate(CMA)can be prepared by extraction of acetic acid from dilute acetic acid wastewater using trioctylamine and then by back extraction using dolomite lime.The effects of extracting agent composition,agent water ratio,extraction temperature and stirring speed on extraction efficiency were studied.The back extraction process conditions were determined.The experimental results show that the process is simpls and effective to recover acetic acid. |
