疏水亲油性植物吸附剂的制备及其应用研究

Paulownia elongata is a widely distributed, high-yield, fast-growing dicotyledon. Its fruit can be used as medicines and wood can be used to make musical instruments. But its leaf hasn't got fully utilized, which causes a waste of resources. The hydrophobicity and lipophilic of paulownia elongate leaf is characterized by static contact water angle (CA), gravimetric, and the morphology and composition is characterized by scanning electron microscopy (SEM), thermogravimetric analysis (TGA). The experimental results show that the reverse side of paulownia elongata leaf possess the better hydrophobic performance and its static contact water angle can reach 131 . Meanwhile, both sides of paulownia elongata leaf has super-oleophilic. The highest saturated oil absorption of dried paulownia elongate leaf can reach 10.7g/g. Thus, it can be used as natural adsorption material.
