| Abstract: | The content of Na 2CO 3 and NaOH or Na 2CO 3 and NaHCO 3 in waste alkali solution which was produced by manufacturing cyclohexanone from benzene was determined with indirect titration and direct titration by means of stripping,so that the interference caused by sodium organic salt in waste alkli solution was avoided effectively.The reliability of the method was tested.The results showed that this method was operated simplely, the determined result was accurate and reliable. |
