摘要
在中学生物教材中,如何证明组织中有无机离子的存在,还没有实验方法的介绍,作者通过研究,摸索出适合中学教学的鉴定组织中无机离子的简易化学方法.实验结果表明:组织细胞中的钙、镁、铁、锌、钾、锰、铜通过专一性的试剂可以产生特殊的颜色反应来证明其存在.
In the biology textbook of high school, there is no recommendations of the experimental methods to identify inorganic salt ions exist in the organization. Through research of this subject,we find out a simple chemical method to identify the inorganic salt ions which is suitable for teaching in secondary school. The results showed that: calcium, magnesium, iron, zinc, potassium, manganese, copper in tissue can be proved its existence by some special reagent which can make them have a special color.
