WebJun 1, 2024 · ClO2 is a red-brown gas [lambda max 36o nm] very different from chlorine. It can be produced by reduction of Chlorate by oxalate in acid and supposedly by disproportionation of chlorate in acid. The latter reaction is questionable as … WebWhereas the pH value of free chlorine should be between 7.2 and 7.4 for optimal disinfection, this is different for chlorine dioxide. In contrast to (free) chlorine, the higher the pH value, the better the disinfection. In …

Webachieve these goals show that chlorine dioxide is more effective than chlorine or monochloramine. Over the pH 6-9 range, chlorine dioxide is at least twice as effective as free chlorine is at pH 6. At pH 7-9, free chlorine becomes progressively less effective than chlorine dioxide. Chlorine dioxide is also substantially more WebDec 8, 2024 · It is effective at pH values between 4 and 10. Its low oxidation potential does not allow it to oxidize organic compounds; that is, it does not break CC or CH bonds. Therefore, unlike free chlorine, it does not form chlorinated organic compounds, as by-products of disinfection (some of these, such as trihalomethanes, are carcinogenic).
