氯气和氨酸钾的制备及性质实验是师范院校化学专业无机化学实验的重要内容。按教材[1]进行实验，药品用量大，实验成本高，废弃物多，污染严重。而且，制得的氯酸钾和次氨酸钠在性质实验中用掉不到1／3，造成浪费。将氯气和氨酸钾的制备实验微型化，可降低成本，减少污染，而且 Preparation of chlorine and potassium and the nature of the experiment is an important part of the chemistry chemistry experiment in normal universities. According to teaching materials [1] experiments, large amount of drugs, high experimental costs, waste and more serious pollution. Moreover, the resulting potassium chlorate and sodium hypochlorite spent less than a third of their experiments in nature, resulting in waste. The miniaturization of the chlorine and potassium potassium production experiments can reduce costs and reduce pollution, moreover
