摘要
找到了用NaOH溶液吸收Cl2的最佳浓度和最佳吸收时间。以ClO和Cl形式保存Cl2不但能避免因Cl2外逸而造成的环境污染,同时延长了Cl2的保存时间,随时可方便地将保存的溶液制成氯水或Cl2,减轻了实验准备人员的劳动强度。该方法对各大中专院校和普通中学化学实验工作具有指导意义。对在水中溶解度小的有害气体的吸收和保存具有参考价值。
The paper finds the best consistency of NaOH solution which absorbs C12 and the best time which is taken to absorb Gl2 with the NaOH solution. To keep C12 with the form of CIO' and Gl-, the environment pollution which is resulted from Cl2 out-come will be prevented, and the time of preserving Gl2 will be lengthened. It is convenient to turn the reserved solution into Cl2 or Cl2 water whenever you want, so lighten the intensity of labor for the people who should prepare for experiments. Since that it's meaningful to use the method to help people carry out the experiments in the labs of the universities and colleges and the Middle Schools. Also it is of reference value to absorb and preserve the poisonous gas which solubility is low in water.
