أكمل القراءةAdd sodium sulfate into the graphitized carbon black cartridge to ca. 1 cm. Activate the cartridge with 10 mL acetonitrile-toluent-acetic acid (75 + 25 + 1, V/V/V) before adding the sample and disposable eluent. Once the solution gets to the top of the sodium sulfate, pipette the eluate into the graphitized carbon black cartridge immediately.
أكمل القراءةsodium sulfur balance will be even more disturbed and the existing means of controlling it will become insufficient. As seen in the vector diagrams, the main sodium loss in a modern process is due to dumped boiler ash in order to control sulfidity, as compared to 1973 when all sodium losses were caused by spills and various washing losses.
