Abstract:

The preparation of ferrous sulfate is a typical inorganic preparative experiment. In accordance with the principles of green chemistry, the experimental method has been improved to achieve comprehensive utilization of waste iron resources, synthesizing ferrous sulfate as an important raw material for anti-anemia drugs, and analyzing and testing it according to pharmacopoeia standards. Students have enhanced their basic experimental skills such as weighing, purification, heating, dissolution, evaporation, crystallization, and solid-liquid separation. They have also recognized the importance of comprehensive utilization of waste resources such as iron and further understood the relationship between iron properties and human health. They have gained an appreciation for the significant role of chemistry in improving the environment, promoting human health, and social development. This experience has strengthened their professional confidence and sense of pride, and has a positive impact on the cultivation of students' abilities and the development of their overall quality.
