【摘要】 通过实验研究 ,定义并测定了吸附型固载二氧化氯的释放特性参数 ,并以临界释放速率UC =0 .0 0 5μg/(h·cm3)作为释放终点 ,将其分为长效、快速和中速释放 3种类型。长效型释放速率峰值Umax <2 0 μg/(h·cm3) ,峰值时间τmax >360h ,有效释放时间τcs >60d ;快速释放型Umax >60 μg/(h·cm3) ,τmax <1 2h ,τcs <7d ;中速释放型则处于两者之间。讨论了固载二氧化氯释放特性的控制方法和不同类型产品的适用范围 ,为产品释放特性的定量研究和应用开发提供了依据。更多还原

【Abstract】 The release characteristic parameter of absorption type solid chlorine dioxide were determined and defined by experimental study.The absorption type solid chlorine dioxide is divided into three types of long-time,fast and moderate speed release in accordance with critical release rate U c =0.005 μg/(h·cm 3) as end release.The release rate peak value U max <20 μg/(h·cm 3).The peak value time τ max >360 h,the effective release time τ cs >60 d for the long-time type;The release rate peak value U max >60 μg/(h·cm 3),the peak value time τ max <12 h,the effctive release time τ cs <7 d for the fast speed release type;It is mean value for the moderate speed release type.The control method of release characteristic and the scope of application of differential types products are discussed.They can provide basis for quantitative study and utilization.更多还原
