摘要
采用平行试验,对液体与固体剂型稳定态二氧化氯消毒应用液的性能进行了比较。结果,作用7min对枯草杆菌黑色变种芽胞杀灭率达100%的二氧化氯浓度,两者分别为130mg/L与200mg/L。将液体、固体原剂置 54℃下存放 2周,二氧化氯下降率分别为 3.5%与 55%。以两者含二氧化氯 500 mg/ L溶液分别浸泡金属片 72 h,液体剂配制液对不锈钢、碳钢、铝与铜的腐蚀速率分别为 0.013、 0.263、0.986、1、067 mm/a,固体剂者分别为0.012、0.910、0.170、0.012 mm/a。
Parallel test was used to compare the Performance between the liquid and the solid formulations of steady-state chlorine dioxide disinfection applied solution. The results indicated that the chlorine dioxide concentrations of these 2 formulations killing 100% of Bacillus subtilis var. niger spores in 7 min were 130 mg / L and 200 mg / L respectively. The chlorine dioxide content in liquid and solid original formulations decreased by 3.5% and 5.5% respectively after storing at 54℃ for 2 weeks. When the solutions of these 2 formulations containing chlorine dioxide 500mg / L were used to immerse metal coupons for 72 h, the corrosion rates of stainless steel, carbon steel, aluminum and copper immersed in liquid formulation solution were 0.013, 0.263, 0.986 and l.067 mm/ a respectively, while those in solid formulation solution were 0.012, 0.910, 0. 170 and 0.012 mm / a respectively.
