摘　　要：采用电-Fenton法和化学Fenton法对淀粉进行氧化,结果可知:电-Fenton法氧化淀粉后,氧化淀粉羧基含量为1.8%,羰基含量为2.4%,黏度为10mPa·s,透光率为40.8%,均优于化学Fenton法氧化的淀粉,红外光谱也证明电-Fenton体系对淀粉氧化程度更深。应用试验也表明电-Fenton氧化淀粉作用生皮胶原,胶原收缩温度为89.0℃,而化学Fenton体系氧化淀粉的胶原收缩温度为83.0℃。The starch was oxidized by electrical Fenton and chemical Fenton method. The results indicate that electrical Fenton method is better than chemical Fenton method. The carbexyl group content is 1.8%, earbenyl group content is 2.4% , viscosity is lOmPa, s and transmittance is 40.8% by electrical Fenton method, which is prior to chemical Fenton. Through application experiments, it is clear the tanned skin collagen has better physical character by electrical Fenton, and shrinkage temperature is 89. 0℃ ,higher than that of electrical Fenton method （ 183.0℃ ）.
