| Abstract: | A pancreatic lipase was crosslinked on the silanized fly ash by glutaraldehyde. The effects of the react time、amount of lipase、and concentration of glutaraldehyde on the activity of the immobilized lipase were studied;and the thermal stability of the immobilized lipase was emphatically studied. At 55℃,the activity of the immobilized lipase was also remained at a high level. |
