【摘要】 <正> 清洗消毒液由次氯酸钠加十二烷基磺酸钠配制而成,其中起杀菌作用的成份主要是次氯酸钠。次氯酸钠具有良好杀菌作用,但稳定性不够理想。欧、美专利介绍,在次氯酸钠中加稳定剂贮存4周,有效氯降解率为10～18%,贮存8周为39～46%。为了解清洗清毒液中次氯酸钠的分解与环境的关系以及一些稳定剂的作用,以改进贮存方法,我们进行了以下的试验。更多还原

【Abstract】 The germicidal detergent was prepared by addition of sodium dodecylsulfonate to sodium hypochlorite. It was indicated in laboratory experiment that when the germicidal detergent was held in a colorless transparent glass bottle put in a place accessible to sunshine, the sodium hypochlorite decomposed rapidly and the available chlorine reduced by 80.31% after half a year and by 95.79% after 1 year. When the bottle was put in a dark place of a cabinet, the available chlorine reduced only by 41.71% after 1 year. When glass bottle or polyethylene bottle was used as the container and put in a sunshine tight cardboard box, the percentage of reduction of available chlorine was similar after 1 year, being only 40%. When brown glass bottle was used to hold the germicidal detergent and put on a table without direct sunshine, the available chlorine reduced also only by 38% or so after 1 year.Addition of 20% tripotassium phosphate or 30 ppm glycine to the germicidal detergent could stabilize sodium hypochlorite in a certain degree更多还原
