Analysis for ozone and residual chlorine by differential pulse polarography of phenylarsine oxide
The differential pulse polarography of phenylarsine oxide has been investigated as an indirect determination of ozone and residual chlorine and compared with standard methods of analysis for these oxidants in water and waste water. The limit of detection for free chlorine at pH 70 is 33 ppb, at pH 4...

| Zusammenfassung: | The differential pulse polarography of phenylarsine oxide has been investigated as an indirect determination of ozone and residual chlorine and compared with standard methods of analysis for these oxidants in water and waste water. The limit of detection for free chlorine at pH 70 is 33 ppb, at pH 4 for total chlorine it is 16 ppb, and for ozone it is 25 ppb at pH 4. The method offers the advantage of fixing free chlorine in the field. |
