摘　　要：实验室利用铜和浓硝酸反应制备NO_(2)时,产生的水易将浓硝酸稀释,导致制备的NO_(2)中含有NO。为了解决该问题,借助滴液式气体发生器进行实验从而制备高纯度的NO_(2)。该实验方法操作简便、安全,并可以控制产气的速度和制备量。When the laboratory uses copper and concentrated nitric acid to prepare NO_(2),the generated water easily dilutes concentrated nitric acid,leading to the product of NO_(2) containing with NO.In order to solve this problem,high purity NO_(2) was prepared by experiments with a drop-type gas generator.The experimental method was simple and safe to operate,and could control the gas production speed and preparation amount.
