【Abstract】 In order to make students understand the properties and uses of agricultural waste wheat straw cellulose, a comprehensive experiment of modification of wheat straw cellulose by oxidation with sodium hypochlorite was designed. The best reaction conditions for modification of wheat straw were discussed, which increased the interest and practicability of the experiment. Students can master the general processing methods of materials, the test and characterization of material properties and the basic operation of some instruments. In addition, the comprehensive experiment was helpful to cultivate students’ spirit of scientific inquiry, environmental awareness, cooperation spirit and social responsibility.更多还原
