摘要：
Photo-degradation alkali lignin was prepared in sunlight by the system of TiO2 and squaraine dye (QSC). The antioxidant activity of photo-degradation was researched. The results showed that the phenolic hydroxyl of degradation alkali lignin is 5.63% with the control is 4.64%, and alcoholic hydroxyl of degradation alkali lignin is 3.21% with the control is 3.77%. The order of antioxidant activity was as following. 2,6-di-tert-butyl-4-methylphenol > high-phenol lignin > the control lignin
