The stability of solid ClO 2 at different temperature,pH,hardness of the washing water,acid—liberation agent、Various surfactants and builders used in the sterilizing—washing agent。The results showed that at temperature below35℃and pH higher than 9 the solid ClO 2 was fairly stable;hardness of the washing water and often used surfactants builders didn't affect the stability of the solid ClO 2;while the powered solid ClO 2 was used,the liberating velocity of ClO 2 was controlled according to adjusting...
